Along with dead Poles, Russians, Ukrainians, etc. (Of course Stalin was doing a good job with those races as well), and in the end without our intervention, most likely we would have been dealing with either an All-Nazi Europe, or an All-Red Europe, neither of which would have been good.
WWII was an inevitable consequence of our totally unjustified intervention in WWI, where no U.S. security interests were involved, but liberal fascist Wilson had to meddle.
Even those obsessed with the survival of Israel need to consider where our intervention in Iraq and elsewhere in the Middle East has led us. Israel is now painted into a corner. Millions of Christians face genocide or exile. Thanks a lot, rich punk G.W. Bush, for listening to the Clintonist CIA director who led you to invade Iraq. Thanks for lying during the campaign that you were against nation-building (in Haiti, right in our hemisphere), then pursuing unprecedented nation-building thousands of miles away.
The country is broke. Wars and interventions inevitably lead to unforeseen adverse consequences. We need to bring the troops home and defend our homeland from illegal immigrants and stop Muslim immigration.
