For many reasons (including the Lebanese war) Israeli-Palestinian conflict is now in the shadow. Regular killings, IDF's raids are going almost unnoticed. Further strickes against Israel would be ineffective and senseless. So the decision is logical. Hamas captured Israeli soldier and in return dozens (if not hundreds) of Palestinians have been killed. But suppose that Hamas would capture American soldiers in Iraq and demand something. Unlikely USAF would bomb Gaza or WB and Israel would not have a moral right to use its military force. It would be a serious problem for our American friends.
