Relations between Truman, Stalin and Attlee (AQA A-Level History): Revision Notes
Relations between Truman, Stalin and Attlee
The Potsdam Conference of July-August 1945 exposed growing tensions between the three Allied leaders. Understanding their individual positions, motivations and mutual suspicions helps explain the breakdown of wartime cooperation and the emergence of Cold War hostility.
The Potsdam context
The day preceding the Potsdam Conference, the USA successfully tested its atomic weapon for the first time. This development profoundly shaped the conference dynamics. Truman viewed this new technology as diplomatic leverage to pressure Stalin into honouring agreements made at Yalta. Stalin interpreted American possession of the atomic bomb as atomic diplomacy—the deliberate use of nuclear capability to intimidate the USSR in international negotiations.
Atomic Diplomacy
The concept of atomic diplomacy refers to the strategic use of nuclear weapons capability as a tool for diplomatic pressure and negotiation. Truman believed the atomic bomb would give the USA a decisive advantage in dealing with Stalin, whilst Stalin viewed this approach as an aggressive attempt at intimidation rather than genuine cooperation.
The conference was marked by Truman's confrontational diplomatic approach and Stalin's unwillingness to be dominated by Foreign Minister Molotov or the USA's nuclear monopoly. Although some agreements emerged regarding Germany, the conference failed to establish any medium- or long-term framework for either Germany's future or the parameters of international relations. Potsdam produced no blueprint for viable, non-confrontational relations between the communist East and capitalist West, leaving suspicion and uncertainty to fester between the USA and the Soviet Union.
Harry Truman's position
Truman's vision for the post-war world mirrored Roosevelt's earlier ideals but was pursued with greater assertiveness. He advocated for:
- National self-determination: allowing peoples to choose their own governments
- An open world trading system based on international economic cooperation
- Global economic reconstruction through institutions like the International Monetary Fund (IMF) and the World Bank
These aims served multiple purposes. Economically, they would prevent the USA from sliding back into the conditions of the Great Depression. Truman understood that closed economies practising autarky—like Italy and the Soviet Union in the 1930s—had been exceptions, protected from the worst effects by not participating in international trade. An open trading system would bind nations together economically, reducing the likelihood of future conflict whilst expanding American markets.
The Great Depression Context
The Great Depression was the severe economic crisis that began with the 1929 Wall Street Crash, when the USA demanded immediate loan repayment from foreign governments, plunging most countries into deeper crisis. Truman's fear of repeating this catastrophe heavily influenced his push for an open, interconnected global economy.
Politically and strategically, Truman's programme fulfilled the USA's ideological commitments to liberal democracy and capitalism. More practically, it addressed geostrategic concerns—Truman aimed to limit the territorial expansion of other states, particularly the USSR, by ensuring American influence in regions of strategic importance.
Truman's changing attitude towards Stalin
Initially, Truman hoped that cooperation could form the basis for US-Soviet relations. He believed America's atomic monopoly would provide sufficient leverage to secure Stalin's compliance over the composition of provisional governments in Eastern Europe. Truman feared Soviet power growth in Eastern Europe, the elimination of anti-communist leaders, and the establishment of pro-communist provisional governments.
The US ambassador to Moscow warned Truman about Soviet expansionism, characterising it as a "barbarian invasion of Europe". Despite these warnings, Truman initially thought diplomatic engagement remained possible.
However, Truman grew increasingly convinced that the USSR would not respond to diplomatic overtures alone. He came to believe that some degree of force might prove necessary to ensure Soviet compliance with American objectives. This represented a deliberate shift from cooperation to confrontation. Truman concluded that this tougher approach was the only language Stalin would understand.
A Critical Shift in US Foreign Policy
Truman's transition from hoping for cooperation to accepting the necessity of confrontation marked a pivotal moment in the origins of the Cold War. This shift from diplomatic engagement to the threat of force fundamentally altered the nature of US-Soviet relations and set the tone for decades of tension to follow.
Joseph Stalin's position
By Potsdam, Stalin had concluded that the USA and its allies represented potential rivals for dominance in post-war Europe. This perception intensified his obsession with Soviet security. Stalin determined that the Red Army must maintain its presence in Eastern Europe, and that pro-communist regimes must be installed throughout the liberated Eastern European states.
The period for cooperation between Stalin and the Western Allies had effectively ended. Whilst Stalin accepted the agreements reached regarding Germany at Potsdam, he harboured a clear but unspoken alternative agenda for the remainder of Europe. Stalin needed Eastern European states to form the foundation of the USSR's long-term security system. This required these states to adopt political and economic systems comparable to the USSR's own. Stalin believed strength derived from unity and a common identity.
Stalin's Security Obsession
Stalin's determination to create a buffer zone of communist states in Eastern Europe was driven by deep-seated fears about Soviet security. The USSR had been invaded through Eastern Europe twice in less than thirty years (World War I and World War II), and Stalin was determined to prevent any future Western threat by ensuring these territories remained under Soviet influence.
Stalin's perception of American intentions
Stalin soon perceived the USA as pursuing an anti-Soviet agenda. This suspicion is evident in a September 1945 note Stalin sent to Molotov, outlining what he believed were America's hidden objectives:
- To divert Soviet attention from the Far East, where the USA positioned itself as "tomorrow's friend of Japan"
- To secure formal USSR acceptance of the USA playing an equivalent role in European affairs to the USSR, enabling America to take control of Europe's future
- To undermine the treaties of alliance the USSR had already negotiated with various European states
- To sabotage any future alliance treaties between the USSR and countries like Romania and Finland
This document reveals Stalin's deep mistrust of American motives and his conviction that the USA sought to dominate Europe at Soviet expense.
Clement Attlee's position
For Britain's new Prime Minister, events since the Yalta Conference had confirmed that Stalin pursued expansionist aims in Europe. Germany's geostrategic significance was paramount for Britain—it was imperative that the USA act as the primary defender of the Western zones against any Soviet threat.
Understanding the Western Zones
The Western zones refer to the occupation zones in Germany administered by Britain, the USA and France following Germany's defeat. These zones became the foundation for West Germany and represented the front line of potential confrontation with Soviet-controlled Eastern Europe.
British foreign policy became explicitly focused on an anti-communist Soviet stance. Attlee supported the terms agreed at Potsdam but remained conscious that these arrangements weakened Germany, at least in the immediate term. A further concern was Potsdam's failure to provide any long-term plan for Germany's future.
This absence of long-term planning became particularly urgent given Stalin's absolute failure to implement his commitments regarding Poland and the Declaration on Liberated Europe made at Yalta. Britain needed American military and economic engagement in Europe to counterbalance Soviet power, but the Potsdam agreements provided no guarantee of sustained American involvement.
Britain's Precarious Position
By 1945, Britain was severely weakened economically and militarily by six years of total war. Attlee understood that Britain could no longer maintain the balance of power in Europe independently. Securing long-term American commitment to European defence became Britain's paramount objective, as without US involvement, Britain would be unable to resist Soviet expansion alone.
Key differences and emerging tensions
The three leaders approached the post-war settlement with fundamentally incompatible visions:
| Leader | Primary goal | Main concern | Approach |
|---|---|---|---|
| Truman | Open markets, liberal democracy | Soviet expansion limiting US influence | Initially cooperative, increasingly confrontational |
| Stalin | Soviet security through buffer states | Western dominance in Europe | Installation of communist governments, rejection of Western interference |
| Attlee | British security, German containment | Soviet expansionism, American withdrawal | Anti-communist stance, encouraging US commitment to Europe |
The atomic bomb's existence amplified these tensions rather than resolving them. Truman saw it as leverage; Stalin saw it as a threat and evidence of American aggression. Neither leader trusted the other's long-term intentions, and both began preparing for confrontation rather than cooperation.
Attlee occupied a more precarious position, dependent on American power to counterbalance the Soviet Union but aware that Britain's weakened post-war state limited its influence over both superpowers.
Key Points to Remember:
- Potsdam marked a turning point: Truman's atomic diplomacy and Stalin's determination created an atmosphere of confrontation, not cooperation.
- Truman shifted from cooperation to confrontation: Initially hopeful about working with Stalin, Truman concluded that force might be necessary to achieve US aims.
- Stalin prioritised Soviet security above all: His unspoken agenda involved creating a buffer zone of pro-communist states in Eastern Europe, regardless of Western objections.
- Attlee needed American engagement: Britain's primary objective was securing long-term US commitment to defending Western Europe against Soviet expansion.
- Mutual mistrust was already entrenched: By September 1945, Stalin believed the USA pursued anti-Soviet objectives, whilst Truman saw Stalin as expansionist and unresponsive to diplomacy.
