They protected from stalin only a half of europe if u dont know and i agree with McNeill. Btw ww2 was almost 100 years ago and imo nothing changed and usa cares only about self interests.
Well, USA was smart enough to protect the better parts of Europe... and WWII was really not a glorious moment for the USA, major corporations profited while people really didn't make good wages at home, and US corporations were the biggest financial proponents of Hitler... Ford, Coca Cola (hi Fanta), Goodyear... the list is enormous but when it boils down to it US corporations made Hitler's tanks (better than they made US tanks...) and fed and entertained Nazi's just for proift.
The real problem with the USA isn't the politics or the people, it's the system which exists in the country and the notion that profit is always greater than people.
