Personally, I think a better approach would be for them to go in and kill Arafat and kill each of the identified members of Hamas and the PFLP members they can find.
And then if others take the place of those killed and the bombings continued, repeat.
Sounds like a good plan to me. I cannot imagine living like the Israelis do everyday. Never knowing when a bomb will go off. I think Israel should do whatever is necessary to keep their citizens safe.
