In his 2024 presidential campaign, Donald Trump promised voters that he would end wars, not start them. Over the past year, he has instead ordered military strikes in seven nations. His appetite for military intervention grows with the eating.

Now he has ordered a new attack against the Islamic Republic of Iran, in cooperation with Israel, and U.S. officials say they expect this attack to be much more extensive than the targeted bombing of nuclear facilities in June. Yet he has offered no credible explanation for why he is risking the lives of our service members and inviting a major reprisal from Iran. Nor has he involved Congress, which the Constitution grants the sole power to declare war. He has issued a series of shifting partial justifications, including his sporadic support for the heroic Iranian people protesting their tyrannical government and his demand that Iran forswear its pursuit of a nuclear weapon.

That Mr. Trump declared the Iranian nuclear program “obliterated” by the strike in June — a claim belied by both U.S. intelligence and this new attack — underscores how little regard Mr. Trump has for his duty to tell the truth when committing American armed forces to battle. It also shows how little faith American citizens should place in his assurances about the goals and results of his growing list of military adventures.

Mr. Trump’s approach to Iran is reckless. His goals are ill-defined. He has failed to line up the international and domestic support that would be necessary to maximize the chances of a successful outcome. He has disregarded both domestic and international law for warfare.

The Iranian regime, to be clear, deserves no sympathy. It has wrought misery since its revolution 47 years ago: on its own people, on its neighbors and around the world. It massacred thousands of protesters this year. It imprisons and executes political dissidents. It oppresses women, L.G.B.T.Q. people and religious minorities. Its leaders have impoverished their own citizens while corruptly enriching themselves. They have proclaimed “Death to America” since coming to power and killed hundreds of U.S. service members in the region, as well as bankrolled terrorism that has killed civilians in the Middle East and as far away as Argentina.

Iran’s government presents a distinct threat because it combines this murderous ideology with nuclear ambitions. Iran has repeatedly defied international inspectors over the years. Since the June attack, the government has shown signs of restarting its pursuit of nuclear weapons technology. American presidents of both parties have rightly made a commitment to preventing Tehran from getting a bomb.

We recognize that fulfilling this commitment could justify military action at some point. For one thing, the consequences of allowing Iran to follow the path of North Korea — and acquire nuclear weapons after years of exploiting international patience — are too great. For another, the costs of confronting Iran over its nuclear program look less imposing than they once did.

Iran, as David Sanger of The Times recently explained, “is going through a period of remarkable military, economic and political weakness.” Since the Oct. 7, 2023, attacks, Israel has reduced the threats from Hamas and Hezbollah (two of Iran’s terrorist proxies), attacked Iran directly and, with help from allies, mostly repelled its response. The new recognition of Iran’s limitations helped give rebels in Syria the confidence to march on Damascus and oust the horrific Assad regime, a longtime Iranian ally. Iran’s government did almost nothing to intervene. This recent history demonstrates that military action, for all its awful costs, can have positive consequences.

A responsible American president could make a plausible argument for further action against Iran. The core of this argument would need to be a clear explanation of the goals — whether they were limited to denying Iran a nuclear weapon or extended to more ambitious aims, like ending its support for terrorist groups — as well as the justification for attacking now. This strategy would involve a promise to seek approval from Congress and to collaborate with international allies.

A responsible approach would also acknowledge the risks that the next conflict with Iran might go less well than the last American attack. Iran remains a heavily militarized country. Its medium-range missiles may have failed to do much damage to Israel last year, but Iran maintains many short-range missiles that could overwhelm any defense system and hit Saudi Arabia, Qatar and other nearby countries. An attack on Iran risks the lives of American troops, diplomats and other people living in the region.

Mr. Trump is not even attempting this approach. He is telling the American people and the world that he expects their blind trust. He has not earned that trust.

Mr. Trump’s failure to articulate either goals or a strategy for a potential military intervention has created shocking levels of uncertainty about this attack. Americans do not know whether the president has ordered an attack in their name mostly to set back Iran’s nuclear program — or to go so far as toppling the government of Supreme Leader Ali Khamenei.

If it is the less ambitious of the two goals, it raises an obvious question. Iran will surely rebuild its nuclear program in the years ahead. So is the United States committing itself to a yearslong cycle of military attacks? If it is the more ambitious goal, Mr. Trump has offered no sense of why the world should expect this effort at regime change to end better than the 21st-century attempts in Iraq and Afghanistan. Those wars toppled governments but understandably soured the American public on open-ended military operations of uncertain national interest, and they embittered the troops who loyally served in them.

Now that the military operation has begun, we wish above all for the safety of the American troops charged with conducting it and for the well-being of the many innocent Iranians who have long suffered under their brutal government. We lament that Mr. Trump is not treating war as the grave matter that it is.
