What isn't open to interpretation however is that it was a joint effort to win WWII. Many nations contributed to that victory. I simply think it is arrogant and insulting for Americans to claim they saved everybody in WWII. It implies that America single handedly came in and did the job. Russia and Britain also saved America in that sense. The implication of this line or reasoning is also that all of Europe and the USSR would have become Nazi Germany. That would have created an enormously powerful empire which together with Japan had been a serious threat to America. It is not like it would have been irrelevant to the US what the outcome would have been.
