Regardless of who, why, or how the Trump Iran War started, one thing is certain: we are going to be fighting it and paying for it for a long time to come.

In the first three weeks of the war, 13 US service members have lost their lives, at least four US airplanes have been destroyed, and the US has spent tens of billions of dollars on this fight. In other countries, hundreds or thousands of people have already been killed, the global energy trade has been disrupted, prices have skyrocketed, and the total cost will never be known.

Rational Americans are—quite correctly—demanding to know why President Trump felt the burning need to launch a hot war when he did, and without consultation with our allies (those same allies, by the way, of whom he is now demanding help to keep the Strait of Hormuz open). Equally important is when and how he sees this war ending: the best comment we have on that so far is that he’ll “feel it in his bones.”

And yet, his opinion of such things has proven—time and again—to be absolutely meaningless. His actions scream that he is operating according to his dreams and his view of “look at me, I’m strong and powerful,” with only barest nod at reality. But even if Donald Trump were to suddenly embrace altruistic, rational thought, and realize that we should no longer be fighting this war, that will not end it.

We’ve kicked over the hornets’ nest that was the religious dictatorship in Iran, but we have not destroyed all the hornets in it. Those with access to weapons in Iran have no reason to stop fighting, even if we do. They’ll keep threatening shipping through the Strait. They’ll keep dropping explosive-laden drones on their neighbors. They’ll keep urging their “proxies” to kill and disrupt as much as possible.

And we’re stuck with it.

Even if a new president took office next week, we’d still have to deal with the insanity launched by Donald Trump’s war of “don’t look at the Trump Epstein files.” Just as he came to office saying “no more forever wars,” such as what we did to Iraq and Afghanistan in the aftermath of the 2001 terror attacks, we’ll be dealing with the Trump Iran War for years to come. Even if Congress somehow manages to cut off funding for this “excursion” of Donald Trump’s, that will only prevent us from inflicting more damage on Iran; it won’t stop the Iranians from a rampaging campaign of revenge for what we’ve done to them in the last few weeks.

So now is the time to figure out—as Arthur Wellesley, the first Duke of Wellington taught us—how to get over this heavy ground as lightly as we can. I fear the only answer is indeed a land war in Asia, in which we send in thousands of ground troops to root out every last adherent of the ruling clique in Iran, and then—as we did in Japan after World War II—set up a US-run government to enable the country to eventually transition into a freedom-loving democracy. It was long and hard in Japan, but we see the results when we don’t do everything necessary: Taliban-run Afghanistan, and the headache that is still Iraq.

And this is the point where I wish I was smarter. Actually I wish our political leaders were even smarter than that, that they could figure out an easy way out of this morass Donald Trump has dumped us into. I fear there isn’t one, and the only way out is through; a long, bloody, soul-rending struggle that Trump has thrown us into for no reason but to soothe his own ego.
