It is fortunate that no one in Israel was hurt, but that was mere luck. People have been killed by these rockets and the fact that Israel warned Gazans is a repeat of what the IDF did to warn before attacks dring Cast Lead. Does any country other than Isreal when attacked by another supply the attackert with water, electricity, food and medical supplies. I think not.
