The Palestinian Authority has
admitted that they could prevent Hamas from further terrorist attacks, but won’t. They feel that "political reasons" prevent them from stopping Hamas.
This just goes to show that the Palestinians don’t want peace. They don’t want their own state. They want Jewish blood. If that requires them to destroy every chance they have at a peaceful and prosperous life for their children, then it appears that they’re willing to do exactly that. It’s suicide warfare on a cultural scale, with the future of the Palestinian people being ripped apart with every new Israeli death.
