The fact is that 60% of the rockets fall in empty areas in Israel or land in Gaza and Israel intercepts 90% of those that would otherwise fall in populated areas, so there is no loss of life on the Israeli side, few injuries and very little property damage. There are neighborhoods in some US cities that are more dangerous than living near the Gaza border. However it is very disturbing and potentially dangerous and Israel could recapture all of Gaza and kill or capture and imprison nearly all the terrorists in short order, but what then? Should Israel then withdraw and allow a new crop of terrorists to organize? Should Israel use thousands of IDF soldiers to police the Gaza, kicking in doors and breaking up meetings, etc. to prevent new groups of terrorists to organize - essentially setting up a police state in Gaza like the ones in Jordan, Saudi Arabia and Iran - while suffering a steady stream of young Israeli soldiers coming home maimed or dead from guerilla attacks? At present, Israel has a lot of noise but few casualties, but destroying the terrorist infrastructure in Gaza would mean less noise but more casualties.
