Explain the steps that led to the long-term involvement of the us in major overseas military commitments NATO Korean war and how did expanding military power and the cold war affect American society?

Answer 1

After the World War I, the United States emerged as one of the world's leading countries, both in military and economy fields. Assuming an ever greater role in the world's events, the US found itself having more and more enemies, be it due to economical or political reasons - which, one might argue - lead to the formation of NATO, US involvement in Korean War and both the World War II and the Cold War.

Answer 2

The US emerged from WW2 as the world's leading economic and military power, with the USSR as the second. Establishing NATO enabled the US to share the risk while leading the fight, while the Korean War was led by the US-UN to deter a North Korean invasion of South Korea. America's lead was due to it's economic and WW2-trained leadership that enabled Pres John Kennedy to say the US would 'pay any price' to maintain democracy.
