There is a far more sensible Israeli response than bombing Gaza, (although I have no problem with Israel bombing Gaza). The most sensible, the most moral, the most effective response of all is annexation. Israel should first seal off Gaza to the media. Then the army should go into Gaza and make the arabs take what they can carry and get out. Kick out the arabs and make Gaza a part of Israel. Once they see how well that works, then they can do the same in Judea and Samaria.
That is the real solution to the arab problem. Airstrikes are just a band-aid.
