To assess the fallout of killing General Suleimani, we must understand that the Iranian regime cannot survive internal dissent or sustain its powerful position in the region if it backs down from this provocation. For Iran’s supreme leader, Ayatollah Ali Khamenei, a strong response is essential. For the United States, the question is: What form will it take and how quickly will it come?
One thing is clear: Americans are not safer, as Secretary of State Mike Pompeo argued on Fox News the morning after. Rather, American citizens are at greater risk of attack across a far wider battlefield than before. That is why the State Department has urged all Americans to depart not only Iraq but also Pakistan, Bahrain and the United Arab Emirates.
In Iraq, Iranian-backed militias have attacked United States and allied installations, and can continue to do so around the country. The government in Baghdad has declared the killing a violation of the terms of the American military presence in Iraq. We will face mounting pressure to withdraw our military and diplomatic personnel from the country. If we leave, the United States will suffer a major strategic defeat: Iran will justifiably claim victory, and the gains of the fight against ISIS will be lost as the terrorist group rebuilds.
There is no hope now to revive, much less strengthen, the Iran nuclear deal, and we must expect Iran will accelerate its efforts to revive its nuclear program without constraint.
