You need to remember that it's NOT all the fault of the palis themselves. You use a very good word here... "Breed." The palis have been hated for many years by the rest of the arabs, for one reason or another. In fact, the only group hated more by the rest of the arabs are the Jews. As such, the palis have been kept in squalor, and fed hatred for Jews (who are blamed for that squalor) since birth. Never mind that it's been the other arab countries that have kept the palis in their squalor, and the UN enabling and contributing to it.
In a very real way, the palis have been "bred" to be nothing more than "cannon fodder" in a war of attrition. It's all they've known for generations. Their entire society, if it can really be called a society, is geared towards hatred of Jews and the destruction of Israel. It can be difficult, if not impossible for an entire society to break out of that sort of psychosis.
