This kind of thing shouldn't surprise anyone. It's been going on a long time and it's not just children's shows in Palestine but mosques in many parts of the Middle East.
There's an old saying "If Palestinians were to lay down their guns tomorrow, there would be no war. If the Jews were to lay down theirs, there would be no Israel." The video above shows why this is so. It's clear that a large segment of Palestinian society would not accept peace on any terms. The bloodshed they inspire is on their hands!
