I find it surprising that you guys don't know that much about WW2 considering the role of the USA. In Germany basically more than 2 years of history lessons are all about 1908 till 1945. But I don't want a history debate right now.
I think overall think the main reason the USA participated with troops is because the Germans attacked the supply ships for the Allies combined with the fear that the remaining scientists could indeed develop atomic bombs...
