In his speech to the U.N. General Assembly, the prime minister of Israel called for the international community, meaning the United States, to draw a red line against Iran's nuclear program. Benjamin Netanyahu did not spell out what that line is, but the clear implication was military action by next spring or summer if Iran does not abandon its uranium enrichment. The United States must categorically reject this invitation to make war on Iran.
The United States has been in a similar position before. In the run-up to the Iraq war, Israel and the neocons in the Bush administration argued that the regime of Saddam Hussein possessed weapons of mass destruction and was a threat to the existence of both Israel and the United States. Neither of those claims was true, but the United States invaded Iraq anyway. Though U.S. forces destroyed Saddam's regime in short order, the tremendous price in American blood and treasure through nine years of fighting did not bring peace or a working democracy to Iraq. In fact, the winner of the war in Iraq was Iran, because the American invasion replaced an implacable enemy of Iran with a weak Shiite regime that Iran can influence.
The United States should not be drawn into a similar mistake now. It should have learned the limits of military power, especially when that power is misapplied.
