Israel helped train and arm the Palestinian police in order to give the West Bank and Gaza more autonomy. When the peace accord in 2000 was rejected, those police officers turned their guns on Israel. Suicide bombings commenced even before that.
It's laughable to read comments from a person that doesn't understand why Israel would re-enter the West Bank terrorist camps. Yes, why would Israelis assassinate terrorist organizers? Why would Israel level the homes of suicide bomber's families? Why would Israel level the structures used to manufacture suicide bombs? And why would Israel set up checkpoints? I mean shouldn't they just allow the suicide bombers free access?
What's wrong bud, did someone shut down your nice NAZI hollocaust denying site, leaving you with no place to play?
