D. The location of the first battle of the American Revolution
This is strictly my opinion but I believe it was a failure. It's original goal was the revitalize the American economy and pull us out of the Great Depression and get American's working again. In this it succeeded to an extent lowering the unemployment rate significantly however it still did not completely work since 15% of the United State's population was still jobless and in poverty. It won't be until WWII and the building of the arms industry as well as army that we will pull ourselves from the Great Depression.
President Truman refused to bomb China because he believed it could lead to a war with the Soviet Union.
Answer:
The reasons why the USSR stole the secret of how to create nuclear warheads can be found in the Cold War.
America, the main adversary of the Soviets during the Cold War period, was a country that had demonstrated its nuclear capabilities to the world in 1945, with the bombings of Hiroshima and Nagasaki. Therefore, it possessed the necessary technology to end an armed conflicts almost immediately and, consequently, its political power was enormous against countries without nuclear capacity.
The Soviet Union, then, had to equate its military forces if it wanted to politically equate itself with the United States. That is, if it managed to have the same threatening power as the United States, it would have similar political power.
