A variety of competing and contradictory theses exist, including: that the Soviet leadership actively sought another great war in Europe to further weaken the capitalist nations; that the USSR pursued a purely defensive policy; or that the USSR tried to avoid becoming entangled in a war, both because Soviet leaders did not feel that they had the military capabilities to conduct strategic operations at that time, and to avoid, in paraphrasing Stalin's words to the 18th Party Congress on March 10, 1939, "pulling other nation's (the UK and France's) chestnuts out of the fire."

However, for a long time the consensus was that those rumors were wrong, and that Soviet-German military negotiations were independent of Rapallo and kept secret from the German Foreign Ministry for some time.

The Polish and French intelligence communities of the 1920s were remarkably well-informed regarding the cooperation. This did not, however, have any immediate effect upon German relations with other European powers. After World War II, the papers of General Hans von Seeckt and memoirs of other German officers became available, and after the dissolution of the Soviet Union

, a handful of Soviet documents regarding this were published.

Alongside the Soviet Union's military and economic assistance, there was also political backing for Germany's aspirations. On July 19, 1920, Victor Kopp told the German Foreign Office that Soviet Russia wanted "a common frontier with Germany, south of Lithuania, approximately on a line with Białystok". In other words, Poland was to be partitioned once again. These promptings were repeated over the years, with the Soviets always anxious to stress that ideological differences between the two governments were of no account; all that mattered was that the two countries were pursuing the same foreign policy objectives.

 fundamentally contributed to the demise of the Weimar Republic. It is, however, disputed whether Hitler's seizure of power came as a surprise to the USSR. Some authors claim that Stalin deliberately aided Hitler's rise by directing the policy of the Communist Party of Germany on a suicidal course in order to foster an inter-imperialist war, a theory dismissed by many others.

During this period, the countries' economic relationship fell as the more isolationist Stalinist regime asserted power and the abandonment of post-World War I military control decreased Germany's reliance on Soviet imports, such that Soviet imports fell to 223 million Reichsmarks by 1934.

The Soviet Union and Nazi Germany before World War II

Moscow's reaction to these steps of Berlin was initially restrained, with the exception of several tentative attacks on the new German government in the Soviet press. However, as the heavy-handed anti-Soviet actions of the German government continued unabated, the Soviets unleashed their own propaganda campaign against the Nazis, but by May the possibility of conflict appeared to have receded.

, and Paul-Emile Naggiar), in an attempt to contain Germany. However, for one reason or another, they were constantly dragged out and proceeded with major delays.

The Western powers believed that war could still be avoided and the USSR, much weakened by the purges, could not act as a main military participant. The USSR more or less disagreed with them on both issues, approaching the negotiations with caution because of the traditional hostility of the capitalist powers. The Soviet Union also engaged in secret talks with Nazi Germany, while conducting official ones with United Kingdom and France. From the beginning of the negotiations with France and Britain Soviet position demanded occupation of Latvia, Estonia and Lithuania. Finland was to be included in Soviet sphere of influence as well. While Britain refused to agree to occupation of the three buffer states by the Soviet Union, Nazi Germany accepted the proposal.

 economic approach or an alliance with England were impossible, closer relations with the Soviet Union were necessary, if not just for economic reasons alone. Germany lacks oil, and could only supply 25 percent of its own needs, leaving Germany 2 million tons short a year and a staggering 10 millions tons below planned mobilization totals, while the Soviet Union was required for numerous key other raw materials, such as ores (including iron and manganese), rubber and food fat and oils. While Soviet imports into Germany had fallen to 52.8 million Reichsmarks in 1937, massive armament production increases and critical raw material shortages caused Germany to turn to reverse their prior attitude, pushing forward economic talks in early 1939. German planners in April and May 1939 feared that, without Russian supplies, Germany would fall critically short of manganese, oil and rubber.

On May 3, 1939, Litvinov was dismissed and Chairman of the Council of People's Commissars (Premier) Vyacheslav Molotov
Vyacheslav Molotov

, who had strained relations with Litvinov, was not of Jewish origin, unlike Litvinov, and had always been sympathetic towards Germany, was put in charge of foreign affairs. The Foreign Affairs Commissariat was purged of Litvinov's supporters and Jews. All this could well have purely internal reasons, but it could also be a signal to Germany that the era of anti-German collective security was past, or a signal to the British and French that Moscow should be taken more seriously in the tripartite alliance negotiations and that it is ready for arrangements without the old baggage of collective security, or even both.

As evident from the German diplomatic correspondence, captured by the American and British armies in 1945 and later published, the reshuffle was warily perceived by Germany as a chance.

It is sometimes argued that Molotov continued the talks with Britain and France to stimulate the Germans into making an offer of a non-aggression treaty and that the triple alliance failed because of the Soviet determination to conclude a pact with Germany. Another existing point of view is that the strive for the triple alliance was sincere and that the Soviet government turned to Germany only when an alliance with the Western powers proved impossible.

Additional factors which drove the Soviet Union towards a rapprochement with Germany might be the signing of a non-aggression pact between Germany, Latvia and Estonia on June 7, 1939 and the threat from Imperial Japan in the East with the Battle of Khalkhin Gol
Battle of Khalkhin Gol

 (May 11 – September 16, 1939). Molotov suggested that the Japanese attack might be inspired by Germany in order to hinder the conclusion of the tripartite alliance.

In July open Soviet-German trade negotiations were under way. In late July and early August, talks between the parties turned to a potential deal, but Soviet negotiators made clear that an economic deal must first be worked out. After Germany had scheduled its invasion of Poland on August 25, and prepared for the resulting war with France, German war planners estimated that a British naval blockade would further exacerbate critical German raw material shortages for which the Soviet Union was the only potential supplier.

Then, on August 3, German Foreign Minister Joachim Ribbentrop outlined a plan where the countries would agree to nonintervention in the others' affairs and would renounce measures aimed at the others' vital interests and that "there was no problem between the Baltic and the Black Sea that could not be solved between the two of us." The Germans stated that "there is one common element in the ideology of Germany, Italy and the Soviet Union: opposition to the capitalist democracies of the West", and explained that their prior hostility toward Soviet Bolshevism had subsided with the changes in the Comintern

 and the Soviet renunciation of a world revolution.

Pact and commercial deal signings


By August 10, the countries had worked out the last minor technical details to make all but final the their economic arrangement, but the Soviets delayed signing that agreement for almost ten days until they were sure that they had reached a political agreement with Germany. The Soviet ambassador explained to German officials that the Soviets had begun their British negotiations "without much enthusiasm" at a time when they felt Germany would not "come to an understanding", and the parallel talks with the British could not be simply broken off when they had been initiated after 'mature consideration.' Meanwhile, every internal German military and economic study had argued that Germany was doomed to defeat without at least Soviet neutrality.

On August 19, the German–Soviet Commercial Agreement (1939) was reached. The agreement covered "current" business, which entailed a Soviet obligation to deliver 180 million Reichsmarks in raw materials in response to German orders, while Germany would allow the Soviets to order 120 million Reichsmarks for German industrial goods. Under the agreement, Germany also granted the Soviet Union a merchandise credit of 200 million Reichsmarks over 7 years to buy German manufactured goods at an extremely favorable interest rate.

On August 22 the secret political negotiations unearthed as well, as it was publicly announced in German newspapers that the Soviet Union and Nazi Germany were about to conclude a non-aggression pact, and the dragged Soviet Triple Alliance negotiations with France and Britain were suspended. The Soviets blamed on the Western powers their reluctance to take the Soviet Union's military assistance seriously and acknowledge the Soviet right to cross Poland and Romania if necessary against their will, as well as their failure to send representatives with more importance and clearly defined powers and the disagreement over the notion of indirect aggression.

on August 24, was met with utter shock and surprise by government leaders and media worldwide, most of whom were aware only of the British-French-Soviet negotiations that had taken place for months. British and French negotiators who were in Moscow negotiating what they thought would be a military potions of an alliance with the Soviet Union were told "no useful purpose can be served in continuing the conversation." On August 25, Hitler told the British ambassador to Berlin that the pact with the Soviets prevented Germany from facing a two front war, changing the strategic situation from that in World War I, and that Britain should accept his demands regarding Poland. Surprising Hitler, Britain signed a mutual-assistance treaty with Poland that day, causing Hitler to delay the planned August 26 invasion of western Poland.

The pact was ratified by the Supreme Soviet of the Soviet Union on August 31, 1939.

Amendment of the Secret Protocols

On September 25, when Hitler was still going to proceed to Lithuania, the Soviet Union proposed to renegotiate the spheres of interest. On September 28, 1939 in Moscow Molotov and Ribbentrop signed the German-Soviet Boundary and Friendship Treaty

, determining the boundary of their respective national interests in the territory of the former Polish state. In a secret supplementary protocol to the treaty the spheres of interest outside Poland were renegotiated, and in exchange for some already captured portions of the Polish territory Germany acknowledged still independent Lithuania part of the Soviet zone.

Expanded commercial pact

Germany and the Soviet Union entered an intricate trade pact on February 11, 1940 that was over four times larger than the one the two countries had signed in August 1939. The trade pact helped Germany to surmount a British blockade of Germany. In the first year, Germany received one million tons of cereals, half a million tons of wheat, 900,000 tons of oil, 100,000 tons of cotton, 500,000 tons of phosphates and considerable amounts of other vital raw materials, along with the transit of one million tons of soybeans from Manchuria. These and other supplies were being transported through Soviet and occupied Polish territories, and this allowed Nazi Germany to circumvent the British naval blockade. The Soviets were to receive a naval cruiser, the plans to the battleship Bismarck

Soviet war with Finland

The last negotiations with Finland had been initiated by the Soviet side as part of its collective security policy in April 1938, and aimed to reach an understanding and to secure a favorable Finnish position in case of a German attack on the Soviet Union through Finnish territory, but this had proven futile due to the Finnish reluctance to break neutrality, and negotiations ended in April 1939, shortly before Litvinov's dismissal. On October 13, 1939 new negotiations started in Moscow, and the Soviet Union (represented by Stalin, Molotov, and Vladimir Potyomkin) presented Finland with proposals including a mutual assistance pact, the lease of the military base of Hanko, and the cession of a 70 km-deep area on the Karelian Isthmus

).

The consequences of the conflict were multiplex. While the invasion revealed the striking military weaknesses of the Red Army and prompted the Soviet Union to reorganize its military forces, and it gained new territories, it pushed neutral Finland towards an accommodation with Nazi Germany, and it dealt yet another blow to the international prestige of the USSR.

Suffering disproportionally high losses compared to the Finnish troops, despite a fourfold Soviet superiority in troops and nearly absolute superiority in heavy weapons and aircraft, the Red Army appeared an easy target, which contributed to Hitler's decision to plan an attack against the Soviet Union.

August tensions

The Finnish and Baltic invasions began a deterioration of relations. Because of tensions caused by these invasions, Germany falling behind in deliveries of goods and Stalin's worries that Hitler's war with the West might end quickly after France signed an armistice

, in August 1940, the Soviet Union briefly suspended its deliveries under the German-Soviet Commercial Agreement. The suspension created significant resource problems for Germany. Ribbentrop wrote a letter promising Stalin that "in the opinion of the Fuhrer... it appears to be the historical mission of the Four Powers -- the Soviet Union, Italy, Japan and Germany -- to adopt a long range-policy and to direct the future development of their peoples into the right channels by delimitation of their interests in a worldwide scale." By the end of August, relations improved again.

 "the historical mission of the Four Powers -- the Soviet Union, Italy, Japan and Germany -- to adopt a long range-policy and to direct the future development of their peoples into the right channels by delimitation of their interests in a worldwide scale." Stalin replied, referencing entering an agreement regarding a "permanent basis" for their "mutual interests." Stalin sent Molotov to Berlin to negotiate the terms for the Soviet Union to join the Axis and potentially enjoy the spoils of the pact.

Ribbentrop asked Molotov to sign another secret protocol with the statement: "The focal point of the territorial aspirations of the Soviet Union would presumably be centered south of the territory of the Soviet Union in the direction of the Indian Ocean." Molotov took the position that he could not take a "definite stand" on this without Stalin's agreement. In response to a written German draft four powers agreement, Stalin presented a written counterproposal, including the Soviets joining the four power Axis if Germany foreclosed acting in the Soviet's sphere of influence. Germany never responded the counterproposal.

January 1941 Border and Commercial Agreement

On January 10, 1941, Germany and the Soviet Union signed an agreement setting several ongoing issues.

 until August 1, 1942, increased deliveries above the levels of year one of that agreement, settled trading rights in the Baltics and Bessarabia, calculated the compensation for German property interests in the Baltic States now occupied by the Soviets and other issues. It also covered the migration to Germany within two and a half months of ethnic Germans and German citizens in Soviet-held Baltic territories, and the migration to the Soviet Union of Baltic and "White Russian" "nationals" in German-held territories. Secret protocols in the new agreement stated that Germany would renounce its claims to one piece of Lithuanian territory in the "Secret Additional Protocols" of the German–Soviet Boundary and Friendship Treaty and would be paid 7.5 million dollars (31.5 million Reichsmark
German reichsmark
The Reichsmark was the currency in Germany from 1924 until June 20, 1948. The Reichsmark was subdivided into 100 Reichspfennig.-History:...

).

From the start of the war until Germany invaded the Soviet Union less than two years later, Stalin supplied Hitler with 1.5 million tons of oil, the same quantity of grain, and many thousands of tons of rubber, timber, phosphates, iron, and other valuable metal ores, particularly chromium, manganese, and platinum. At the time of the invasion, Nazi Germany was heavily in debt to the Soviet Union. Russian historians dispute the importance of the Soviet Union's trade with Germany. They point out that in mid-1941 Germany's oil resources totalled 10 million tons: of these 500,000 were produced in Germany proper, 800,000 by the countries occupied by Germany, and 8,700,000 tons by Germany's European allies, with Romania accounting for the bulk of this amount.

Mid-1941 relations

In an effort to demonstrate peaceful intentions toward Germany, on April 13, 1941, the Soviets signed a neutrality pact with Axis power Japan. While Stalin had little faith in Japan's commitment to neutrality, he felt that the pact was important for its political symbolism, to reinforce a public affection for Germany.

Stalin felt that there was a growing split in German circles about whether Germany should initiate a war with the Soviet Union. Stalin did not know that Hitler had been secretly discussing an invasion of the Soviet Union since the summer of 1940, and that Hitler had ordered his military in late 1940 to prepare for war in the east regardless of the parties talks of a potential Soviet entry as a fourth Axis Power.

Further development

In western Europe, Nazi Germany was engaged in their conflicts, especially after its April 9, 1940, Germany invasion of Denmark and Norway. On May 15, the Netherlands capitulated. By June 2, Germany had occupied Belgium. On June 14, Wehrmacht entered Paris. On June 22, France surrendered.

Had the Soviet Union joined the Anglo-French blockade, the German war economy would have soon collapsed. With its own raw materials as of September 1939, Germany could have only been supplied for mere 9 to 12 months.

According to Mr. Rapoport, "one of Stalin's first gifts to the Nazis was to turn over some 600 German Communists, most of them Jews, to the Gestapo at Brest-Litovsk in German-occupied Poland.". The Soviets also offered support to the Nazis in official statements, Joseph Stalin

 on June 22, 1941. After the launch of the invasion, the territories gained by the Soviet Union due to the Molotov–Ribbentrop Pact were lost in a matter of weeks. In the three weeks following the Pact's breaking, attempting to defend against large German advances, the Soviet Union suffered 750,000 casualties, and lost 10,000 tanks and 4,000 aircraft. Within six months, the Soviet military had suffered 4.3 million casualties and the Germans had captured three million Soviet prisoners, two million of which would die in German captivity by February 1942. German forces had advanced 1,050 miles (1,690 kilometers), and maintained a linearly-measured front of 1,900 miles (3,058 kilometers).

Denial of the Secret Protocol's existence by the Soviet Union

German officials found a microfilmed copy of the secret protocols of the Motolotv-Ribbentrop Pact in 1945 and provided it to United States military forces. Despite publication of the recovered copy in western media, for decades it was the official policy of the Soviet Union to deny the existence of the secret protocol.

Post-war commentary regarding the timing of Soviet-German rapprochement

After the war, historians have argued about the start of Soviet-German rapprochement. There are many conflicting points of view in historiography as to when the Soviet side began to seek rapprochement and when the secret political negotiations started.

Some scholars argue that for a long time the collective security doctrine was a sincere and unanimous position of the Soviet leadership, pursuing a purely defensive line, while others contend that from the very beginning the Soviet Union was aimed at the cooperation with Nazi Germany, collective security being merely tactical counter to some unfriendly German moves. However, it might well be the case that Moscow sought to avoid a great war in Europe because it was not strong enough to fight an offensive, but there was much disagreement over the policy between Litvinov and Molotov as to how to attain the goal, and Stalin balanced between their positions, starting pursuing both contradictory lines simultaneously quite early and abandoned collective security only at some point in 1939.

Nazi Germany started its quest for a pact with the Soviet Union at some point in the spring of 1939 in order to prevent an Anglo-Soviet-French alliance and secure Soviet neutrality in a future Polish-German war.

Some argue that the rapprochement could start as early as in 1935-1936, when Soviet trade representative in Berlin David Kandelaki made attempts at political negotiations on behalf of Stalin and Molotov, behind Litvinov's back. Molotov's speech to the Central Executive Committee of the Supreme Soviet in January 1936 is usually taken to mark this change of policy. Thus, Litvinov's anti-German line did not enjoy unanimous support by the Soviet leadership long before his dismissal. Walter Krivitsky

 agent, who defected in the Netherlands in 1937, reported in his memoires in 1938 that already then Stalin had sought better relations with Germany. According to other historians, these were merely responses to German overtures for détente.

It is also possible that the change of foreign policy occurred in 1938, after the Munich Agreement, which became the final defeat of Litvinov's anti-German policy of collective security, which was marked by the reported remark about an inevitable fourth partition of Poland

According to others, the first sign of a Soviet-German political détente was the conversation between Soviet ambassador Aleksey Merekalov and Ernst von Weizsäcker

, recently released documents from the Soviet diplomatic show that western historians have been mistaken in assuming that the Merekalov-Weiszäcker meeting of April 1939 was the occasion for Soviet signals of a desire for détente with Nazi Germany. His point of view, supported by Derek Watson and Jonathan Haslam is that it was not until the end of July 1939 – August 1939 that the policy change occurred and that it was a consequence rather than a cause of the breakdown of the Anglo-Soviet-French triple alliance negotiations. It must have been clear to Molotov and Stalin in August 1939, that an agreement with Germany avoided an immediate war with that country and could satisfy Soviet territorial ambitions in eastern Poland, Estonia, Latvia, Lithuania, Finland, and Bessarabia; an alliance with Britain and France offered no territorial gains and a war with Germany in which the USSR was most likely to bear the brunt of a German attack.
