Don't you remember the hoopla about the Palestinian boy having allegedly been killed by Israeli troops in a shootout (the one that was photographed near his father)? When the dust settled, it turned out he was killed by fellow Palestinians. No sacrifice is too small for terrorists. Soviet communists did the same during the "Red terror" campaign.
Terrorists will sacrifice anything, including children --- even their own. That is the lesson the West has never learned about totalitarian ideologies.
