An article in Middle East Quarterly purports to show the amount of foreign aid given to the Palestinians tracks with the number of homicides committed there.
In the midst of the effort in Paris to bestow unprecedented sums of foreign aid on the Palestinians, there was little discussion of the unintended consequences — often deadly ones — of previous aid regimens. The recent history of foreign assistance shows a distinct correlation between aid and violence. Perhaps aid itself does not cause violence, but there is strong evidence that it contributes to a culture of corruption, government malfeasance, and terrorism that has had lethal consequences for both Israelis and Palestinians over the past decade.
This is actually somewhat unsurprising. If you have to work long hours just to support yourself, it's unlikely that you have time for "extracurricular" activities.
Contra the Jimmy Carter position (outlined so ably by the anti-Semite himself in the post below), there will be no opportunity for peace between Israelis and Palestinians until you have a couple of generations of Palestinians raised in something other than the toxic, Jew-hating crucible of the U.N.-run school system.
