Who is the terrorist?

"Since November, Israel has killed four Palestinians and wounded 66. Israel’s tanks have rolled into Gaza or its snipers have fired on average once a day since the ceasefire. Hamas has managed to stop its militants and those of the smaller and more extreme Islamic Jihad group from launching any rockets into Israel—until late last month, after the death of a Palestinian prisoner in Israeli custody, which prompted them to fire three rockets into Israel. The Israelis retaliated by cutting off Gaza’s already tightly controlled flow of supplies through the crossings."
