The War On Iran Has Four Possible Outcomes

Only one of these four paths protects humanity—the other three are likely destroy it.

This week Donald Trump threatened more war crimes on the people of Iran.

We are now in the most dangerous phase of this crisis, and pretending otherwise is reckless. As a human rights lawyer, I do not view war as an abstraction, a chessboard, or a television spectacle. I view it in terms of law, civilian life, state accountability, and foreseeable human devastation. If we are honest about the present moment, there are only four plausible scenarios from here. Three are catastrophic. The fourth is the only one consistent with constitutional government, international law, and basic human survival. It is also the one Donald Trump appears least willing to accept—but one our Congress must rally to ensure happens. Let’s Address This.

Trump’s War Crimes Threat

As of Monday this week the United States’ and Israel’s illegal war on Iran has killed 1,200 Iranians, mostly civilians. Up to one third of them are children—including the near 175 children killed by a U.S. military Tomahawk missile. Iran’s response has targeted military bases, resulting in reportedly 6 U.S. soldiers killed and 13 Israelis. Now, Trump is promising “Death, Fire, and Fury” and “twenty times” the damage if Iran does not unconditionally surrender.

In other words, we are running out of time to end this illegal war and prevent global and irreparable catastrophe. Right now we have four possible paths ahead of us. It is critical we rally and demand Congress act to enact Option Number Four.

Option One

The first scenario is that Trump eventually admits defeat and withdraws from Iran. In purely human terms, that would be preferable to escalation, but it would still come after an illegal war already launched without constitutional authority and under a pretext that has not been substantiated. The geopolitical consequences would be significant.

A failed American war would further erode U.S. credibility and likely accelerate a broader shift in influence toward China and Russia. Iran, having survived direct U.S.-Israeli assault, would emerge emboldened. Oil may no longer be pegged to the U.S. dollar as the global currency, devastating the US economy. None of this is favorable, though this is the bed Trump has made so far. But also, compared with what comes next, it is survivable.

Option Two

The second scenario is a ground invasion. Trump has not ruled that out. He has not ruled out a draft either. The Pentagon is already reportedly preparing to seek roughly $50 billion in supplemental funding for Middle East operations, a strong indication that the administration is contemplating a longer and more expensive war footing. A quick reminder that politicians lie when they say we cannot afford to fund universal healthcare, free public college, free school lunches, or affordable housing.

Anyone speaking casually about invading Iran is either ignorant of the facts or indifferent to the lives that would be destroyed. Invading Afghanistan and Iraq was already catastrophic. As I’ve cited before, a Brown University study documents an estimated 4.6 million civilians killed by western wars since 2001.

And Iran is not Iraq. Iran is about 1.63 million square kilometers—which is triple the size of Iraq. I has a population that recent estimates place in the low 90 million range—which is double that of Iraq. It’s largest city, Tehran, has a population of 9.6 million—larger than New York City. It is geographically vast, heavily populated, politically complex, and militarily formidable.

A U.S. ground invasion would not be a quick operation. It would be a regional inferno. Potentially millions could die. The global economy would likely be pushed into a prolonged recession. And because major powers would not passively watch such a war unfold, the risk of a broader world war would rise dramatically. Thus, option three.

Option Three

The third scenario is the use of nuclear weapons by Israel or the United States. That is the scenario many people still resist discussing openly because it sounds too horrible to contemplate. But refusing to contemplate it does not make it less real. This is not hyperbole. Research published in Nature Food and highlighted by Rutgers found that a large-scale nuclear war could kill more than 5 billion people through famine and system-wide collapse, even apart from the immediate blast deaths. In ordinary language, that means the deaths of four to six billion human beings within a relatively short period are well within the range of expert projections in a full nuclear exchange. It would be worse than any Hollywood film can imagine because movies still assume that civilization survives in recognizable form. Nuclear war does not promise survival. It promises planetary ruin. Thus, we must push for Option Four.

Option Four

That leaves the fourth scenario, which is the only morally serious option: Trump resigns or is impeached, the war is halted, and actual peace negotiations begin. With Trump removed from power, there is at least a possibility of returning to diplomacy, de-escalation, and meaningful non-proliferation efforts. History gives us a model. In the mid-1980s, the United States and Soviet Union moved from existential nuclear hostility toward negotiations that helped reduce the risk of annihilation. That kind of diplomacy is still possible, but only if the men driving this escalation are stopped. The obstacle, of course, is political cowardice. This would require the Republican Party to develop a spine and fulfill its constitutional duty. It would require Corporate Democrats to grow a spine and demand an end to this war. Instead, Hakeem Jeffries refuses to rule out funding this illegal attack on Iran with another $50B.

At present, it seems unlikely that Republicans and Corporate Democrats will grow a spine or a conscience. But unlikelihood is not an excuse for silence when the alternative is mass death.

Conclusion

Here’s the bottom line. This is not red versus blue. This is not left versus right. This is working people versus billionaires, civilians versus war planners, constitutional government versus authoritarian impulse. This is why the culture wars must stop. Because as bad as things are, they can get much worse. Trump has not ruled out the worst options. He has not ruled out sending American troops into a catastrophic ground war. He has not ruled out escalating further. He has already shown that he will ignore constitutional limits, and too many members of Congress still behave as though strongly worded statements are an adequate response to an unlawful war.

There is also a deeper pattern here that should disturb every serious observer. In 2013, Trump claimed Obama would bomb Iran to distract from his failures. In 2023, J.D. Vance warned against repeating in Iran the same mistake made in Iraq. Now they are doing exactly what they accused others of doing. That is not irony. It is the operating logic of fascist politics: accuse the other side of the crime you are preparing to commit yourself.

The legal and moral stakes are immense. Congress must act now to stop this war, cut off funding for unauthorized escalation, and reassert that the Constitution is not optional. Military service members must also remember that “I was just following orders” did not excuse unlawful conduct at Nuremberg, and it will not excuse it now. To those cheering this war from a distance, understand what you are cheering for: possible nuclear confrontation, higher prices for families already struggling, and the deaths of ordinary soldiers while the sons of powerful men remain far from the battlefield.

We need option four, and we need it immediately. Trump must be removed from the machinery of war before his recklessness becomes irreversible. If we fail to stop this now, history will not say we were uninformed. It will say we were warned and did too little.
