I say no. Hamas are more prepared to fight in head to head battle. Pounding them from the sky will save Israeli lives.
Sending ground troops into Lebanon did not do any good either.
Unless they know where Shalit is, I say definitely no to a ground operation.
I also say to definitely leave Hamas in power. This will ensure that Gaza and WB remain 2 separate entities and no foreign power will be able to force Israel to cut itself in half.
