Question

Why was the United Nations welcomed by Americans and Congress versus the League of Nations after WWI?

Answer 1

WWI was considered by many to be "the War to End all Wars" so no one at the time felt there was a need to have an organization such as the league of Nations.  Also after WWI the United States adopted isolationism as their form of foreign policy, so many politicians at the time saw no need to waste the resources.  After WWII the many countries felt the need to endorse the United Nations as a preventative measure to deter future wars like the World Wars.

Answer 2

Different circumstances, different eras.  After WWI, the US was primarily isolationist with regards to its foreign policy. The British Empire was still there to be the world's dominant power.  After WWII, the US found itself the dominant millitary power and faced with a powerful ideological enemy; the Soviet Union.  The US knew it could not turn its back on the world but it also didn't want to face a future of perpetual warfare, possibly with nukes.  The UN seemed the best way for the US to promote its international interests and oppose its enemies.

PS: this is not an declaration of support for the UN.  As far as establishments go, a library could be written about its faults and failures.

Answer 3

The League Of Nations had the appearance more of a trading club. The League Of Nations did not prevent The War . This was not the purpose of The League.  The U.N. was built for the purpose of stopping genocide  and unprovoked attacks on other countries like that in WW2. The idea was to make war less possible even stop the agressor from attacking the other country. The U.N. was built on the idea of protecting and supporting Human Rights.
