It hasn't worked. Iran has rejected repeated offers of technical and economic assistance, most recently this month. Despite four years of pleading, the Administration has failed to win anything but weak U.N. sanctions.
Israelis surely don't welcome a war in which they will suffer. Yet they have no choice but to defend themselves against an enemy that vows to obliterate them if Iran acquires the weapon to do so. The tragic paradox of the past six years is that the diplomatic and intelligence evasions offered in the name of avoiding war with Iran have done the most to bring us close to this brink. Appeasement that ends in war is a familiar theme of history.
