androbot2084: "...If we really think about it there is probably a lot of alternatives to violence during World War 2.
By very definition of the term, "World War II" is violence on a global scale; not 'non-violence'.

androbot2984: "The United States could have accepted Jewish refugees but instead turned them back because we did not want any more illegal aliens."
-Your opinion is illogical because "refugee" and "illegal alien" are unrelated in terms of legal status defined by law. A "refugee" is not by definition an "illegal alien".
-Furthermore, you state that the United States "did not want any more illegal aliens", yet there was no significant influx of illegal aliens into the United States until the 1950's when President Eisenhower responded to a flood of illegal Mexicans by launching "Operation Wetback".
Prior to this time the United States allowed organized and legal immigration into the U.S., primarily from Western Europe.

androbot2084: "...However we must ask ourselves are their any victors in war?
-The answer to this question is YES.
-The ALLIES emerged victorious...the USSR was one of the ALLIES.
-The USSR not only defeated a massive Nazi surprise attack & invasion of its homeland, but counterattacked, occupying half of Germany and surrounding Berlin.
-Had the American led Normandy Invasion not taken place, the USSR might have not only emerged victorious in its "Great Patriotic War", but pushed all the way to the Atlantic Ocean as well.

androbot2084: "After the Germans were defeated we had a constant threat of nuclear war with the Russians"
-Incorrect. It was only years later that the Soviets acquired the ability to produce a nuclear device.
-The "Mexican standoff" which resulted from the threat of mutual annihilation is what prevented open military conflict between the U.S.A. and the USSR, due in no small part to the fact that both nations shared the goals of acquiring material wealth and increasing their own standards of living. The result was "war by proxy" where both sides used smaller and potentially less dangerous countries around the world to fight each other in attempts to prove ideological superiority.
