I might be wrong (am not a geopolitical expert) but my guess is that if the US doesn't get this resolved by itself; most countries in the world are going to rage at it harder (like an order of magnitude harder) than during the tariffs war of last year.

Many countries ranging from advanced allies like Japan to random poor countries like the Philippines will see economic damages that are way worse than tariffs.

Iran was a hornet nest. A hornet nest is annoying and dangerous to have around. But it makes no sense to break it open with no plan on how to properly handle the fallout.
