I wonder what the American left would do if Israel were overrun by the Muslims. We know Hamas would proceed to murder every last Jewish man, women, and child and lots of Muslim Israelis too...in Nazi fashion. Would the left do anything to stop the bloodshed? I think not.
I base my opinion on what the Left did in SE Asia when the commies overran Vietnam and Cambodia murdering millions because the liberals in Congress reneged on our promise to support S. Vietnam. And look what the Left's biggest hero (FDR) did to Eastern Europe. He enslaved them to 50 years of domination and suffering by the commie Soviets. When you add in the Left's hatred of Israel and admiration of Hamas, it is easy to conclude that Hitler's Final Solution could be accomplished, while the Left willfully looks away.
The Israelis must know the USA run by liberals is not an ally to be counted on.
