President Donald Trump has done what he swore he would not do: involve the United States in a war in the Middle East. His supporters will tie themselves in knots (as Vice President J. D. Vance did last week) trying to jam the square peg of Trump’s promises into the round hole of his actions. And many of them may avoid calling this “war” at all, even though that’s what Trump himself called it tonight. They will want to see it as a quick win against an obstinate regime that will eventually declare bygones and come to the table. But whether bombing Iran was a good idea or a bad idea—and it could turn out to be either, or both—it is war by any definition of the term, and something Trump had vowed he would avoid.
So what’s next? Before considering the range of possibilities, it’s important to recognize how much we cannot know at this moment. The president’s statement tonight was a farrago of contradictions: He said, for example, that the main Iranian nuclear sites were “completely and totally obliterated”—but it will take time to assess the damage, and he has no way of knowing this. He claimed that the Iranian program has been destroyed—but added that there are still “many targets” left. He said that Iran could suffer even more in the coming days—but the White House has reportedly assured Iran through back channels that these strikes were, basically, a one-and-done, and that no further U.S. action is forthcoming.
(In a strange moment, Trump added: “I want to just say, we love you, God, and we love our great military.” Presidents regularly ask God to bless the American nation and its military forces—as Trump did in his next utterance—but it was a bit unnerving to see a commander in chief order a major military action and then declare how much “we” love the Creator.)
Only one outcome is certain: Hypocrisy in the region and around the world will reach galactic levels as nations wring their hands and silently pray that the B-2s carrying the bunker-buster bombs did their job.
Beyond that, the most optimistic view is that the introduction of American muscle into this war will produce a humiliating end to Iran’s long-standing nuclear ambitions, enable more political disorder in Iran, and finally create the conditions for the fall of the mullahs. This may have been the Israeli plan from the start: Despite Israeli Prime Minister Benjamin Netanyahu’s warnings about the imminence of an Iranian nuclear-weapons capability and the need to engage in preemption, this was a preventive war. The Israelis could not destroy sites such as Fordow without the Americans. Israeli military actions suggest that Netanyahu was trying to increase the chances of regime change in Tehran while making a side bet on dragging Trump into the fray and outsourcing the tougher nuclear targets to the United States.
The very worst outcome is the polar opposite of the optimistic case. In this bleak alternative, the Air Force either didn’t find, or couldn’t destroy, all of the key parts of the Iranian program; the Iranians then try to sprint across the finish line to a bomb. In the meantime, Tehran lashes out against U.S. targets in the region and closes the Strait of Hormuz. The Iranian opposition fades in importance as angry Iranian citizens take their government’s part.
One dangerous possibility in this pessimistic scenario is that the Iranians do real damage to American assets or kill a number of U.S. servicepeople, and Trump, confused and enraged, tries to widen his war against a country more than twice the size of Iraq.
Perhaps the most likely outcome, however, is more mixed. The Iranian program may not be completely destroyed, but if the intelligence was accurate and the bombers hit their targets, Tehran’s nuclear clock has likely been set back years. (This in itself is a good thing; whether it is worth the risks Trump has taken is another question.) The Iranian people will likely rally around the flag and the regime, but the real question is whether that effect will last.
The Iranian regime will be wounded, but will likely survive; the nuclear program will be delayed, but will likely continue; the region will become more unstable but is unlikely to erupt into a full-blown war involving the United States.
But plenty of wild cards are in the deck.
First, as strategists and military planners always warn, the “enemy gets a vote.” The Iranians may respond in ways the U.S. does not expect. The classic wargaming mistake is to assume that your opponent will respond in ways that fit nicely with your own plans and capabilities. But the Iranians have had a long time to think about this eventuality; they may have schemes ready that the U.S. has not foreseen. (Why not spread around radiological debris, for example, and then blame the Americans for a near-disaster?) Trump has issued a warning to Iran not to react, but what might count as “reacting?”
Second, we cannot know the subsequent effects of an American attack. For now, other Middle Eastern regimes may be relieved to see Iran’s nuclear clock turned back. But if the Iranian regime survives and continues even a limited nuclear program, those same nations may sour on what they will see as an unsuccessful plan hatched in Jerusalem and carried out by Washington.
Diplomacy elsewhere will likely suffer. The Russians have been pounding Ukraine with even greater viciousness than usual all week, and now may wave away the last of Trump’s feckless attempts to end the war. Other nations might see American planes flying over Iran and think that the North Koreans had the right idea all along: Assemble a few crude nuclear weapons as fast as you can to deter further attempts to end your regime.
Finally, the chances for misperception and accidents are now higher than they were yesterday. In 1965, the United States widened the war in Southeast Asia after two purported attacks from North Vietnam; the Americans were not sure at the time that both of them had actually happened, and as it turns out, one of them probably did not. The region, moreover, is full of opportunities for screw-ups and mistakes: If Trump continues action against Iran, he will need excellent intelligence and tight organization at the Pentagon.
And this is where the American strikes were really a gamble: They were undertaken by a White House national security team staffed by unqualified appointees, some of whom—including the Director of National Intelligence and the Secretary of Defense himself—Trump has reportedly frozen out of his inner circle. (Given that those agencies are run by Tulsi Gabbard and Pete Hegseth, it is both terrifying and a relief to know that they have no real influence.) The American defense and intelligence communities are excellent, but they can only function for so long without competent leadership.
Trump has had preternatural luck as a president: He has survived scandals, major policy failures, and even impeachment, events that would have ended other administrations.The American planes dropped their payloads and returned home safely. So he might skate past this war, even if it will be hard to explain to the MAGA faithful who believed him, as they always do, that he was the peace candidate. But perhaps the biggest and most unpredictable gamble Trump took in bombing Iran was to send American forces into harm’s way in the Middle East with a team that was never supposed to be in charge of an actual war.
