Sem2.HW1

If the US did not continue to test and improve it's nuclear capability after the WW2, which broke the balance of weaponry power of the world, Soviet Union would not feel urged to improve their atomic power, then there may be a chance to avoid the Cold War.

The Iron Curtain created more coldness between the Soviet Union and the US. If Stalin cared more about the speech about iron curtain by Churchill, and avoided potential communist takeovers which raise the unhappiness and anger of the US, the Cold War may not have happened.

If Truman Doctrine (1947) was not announced, the Soviet would not feel threaten by the US, which created more coldness between the two nations. Consequently, the Cold War might be avoided.
