You are so ignorant it's absurd... lol.
It's not "anti-American propaganda" to realize the unique position America was in 1945.
The richest countries in the world in 1940 were:
1. USA
2. USSR
3. Germany
4. UK
5. Japan
China was in the mix as well. Can you think of anything at all that happened to China, the USSR, Germany, the UK, and Japan between 1933 and 1945?
Anything at all?
Half of the USSR was destroyed along with a huge percentage of it's population.
ALL of Germany was destroyed. along with a huge percentage of it's male population.
The UK lost it's empire from where most of it's wealth came from.
Japan was destroyed and lost a huge percentage of it's population.
China was brutalized by Japan for over a decade and immediately fell into civil war once the war was over with tens of millions killed.
Meanwhile, the US was completely untouched suffered WAAAAAAAY less casualties than anyone else as a percentage of population and the civilian population was completely untouched.
This set the US up for the economic boom more than any other reason. To suggest otherwise is absurd.
Imagine half the NFL being killed in plane crashes and then the only team which didn't lose half it's players shows up on Sunday and claims they won their game because they executed better than their opponent... You're being ridiculous.
