Netanyahu will claim they had no choice if they were to free Shalit, but the coming terrorism is too great a price to pay for Shalit's freedom. Even Shalit will come to condemn this exchange.
Israel is roundly condemned for its continuing settlement activity, the anti-Israel Arab Street is rising in power, Israel's relations with Turkey are in shambles, etc. The death of large numbers of unarmed, innocent Israeli civilians could change this PR nightmare.

See the Senate Foreign Relations Committee's 11/30/2009 Report on Tora Bora.

I'm a Vietnam era veteran. I didn't fight, but I did volunteer to fight - for nothing in Vietnam. I'm sure as hell willing to fight for American ideals in America. Next war, civil war.
