I'm not sure what definition of "peaceful" you're going with here, if it includes any of the US, Iran, or Israel, prior to the start of this war. I guess I'm not as sophisticated as you.
> Strange how you say the US is not peaceful, immediately followed by an argument why US's attack not only leads to peace, but the "non-attacking" nation must be defeated for peace. Which I'm sure we'll agree requires more violence. In fact your argument that Iran "defending itself" leads directly to a bigger war is accurate, I think.
I'm not sure why you think that's strange. There was a status quo: Iran lets ships through the Strait of Hormuz. It works well enough. Then the US attacked, and that status quo is gone. If the US ends this war without re-establishing the status quo, then the world will be worse for everyone, and other nations bordering critical shipping lanes will be encouraged to follow suit.
So it's better for everybody if the US wins. But the US doesn't have much leverage to do so, and so the situation is: the US started a war that it didn't need to start, but can't easily win. The foreign policies that built the Pax Americana have been abandoned.
