If there were any truth to this claim, Europe would be flooded with Arab refugees from Israel and/or "Palestine". That clearly isn't the case.
Rather, the worst refuge crisis since World War II is currently caused by Arabs fleeing Arab League states. These states are in turmoil from Muslims killing Muslims for not being Muslim ENOUGH.
If the Jewish State were so brutal (as Abbas claims), Arabs would be fleeing "Israeli Occupied Territory" en masse along with all the Iraqis, Syrians, Libyans, Somalis etc. Since that is not the case, Abbas' claims are clearly a deliberate lie.
Why do Europeans listen politely to Abbas' lies? I think I know the answer, but it doesn't matter. The mere fact that a lie of this magnitude goes unchallenged tells me all I need to know.
