On the Fact that There Were Tens of Millions of Displaced People In the Years Following WW1 and WW2 (12 Million Ethnic Germans Being Expelled from Eastern Europe, India and Pakistan Exchanging 14 Million People, Turkey and Greece Exchanging 2 Million, 7 Million People In the Balkans Being Displaced, and Last but Not Least Over a Half Million Jews Having to Flee Arab Countries) and the Only Ones Not to Be Repatriated Were the Palestinians

 I suppose that you could blame Israel (it's the fallback position for many on the hard left these days - yes, that lackluster they've become) but the fact that the entire Arab world didn't lift a finger to assist these poor people is a bit of an indictment, too, wouldn't you say? I surely would (especially since it was these very same Arab countries that prompted a lot of them to leave in the first place).
