North America 1949: North Atlantic Treaty
World War II left the United States and the Soviet Union as the dominant powers in Europe. Relations between the two began to deteriorate almost immediately, especially after US concerns over the Soviet installment of Communist regimes in Eastern Europe prompted President Truman to embark on a policy of “containment” by aiding the non-Communist regimes which surrounded the Soviet bloc. As this new “Cold War” heated up, the US and its European allies signed the North Atlantic Treaty, formally creating the NATO alliance to counter any potential Soviet attack.
30 Mar 1946-16 Oct 1949 Greek Civil War▲
After the Axis powers occupied Greece, the Greek contingent of the allied war effort became divided between the government-in-exile of King George II’s and the predominantly Communist partisans which oversaw the German withdrawal in 1944. Following the war’s end, the Communist Party reorganized into the Democratic Army of Greece (DSE) and fought a guerilla war against the Kingdom, but collapsed in 1948 due to lack of foreign support.
12 Mar 1947 Truman Doctrine▲
In an address to United States Congress, President Harry Truman outlined his policy of supporting “free peoples” against “attempted subjugation armed minorities or by outside pressures”, insisting the US assist them “primarily through economic and financial aid”. The speech was an attack on Soviet attempts to destabilize Greece and Turkey, leading the US to give financial support to those nations. As a general policy of containing Soviet expansionism by backing those it threatened, this so-called Truman Doctrine would become the foundation of US foreign policy during the Cold War.

31 Mar 1948 Marshall Plan▲
Following World War II, US Secretary of State Gen. George Marshall developed a plan to aid the reconstruction of allied and occupied countries in Europe, passing as the Foreign Assistance Act in 1948.

Eight days later, at midnight on 31 March, Newfoundland and its dependency of Labrador joined Canada as its tenth province, Newfoundland. In return, Canada took over much of Newfoundland’s infrastructure and assumed responsibility for its debt.
