How and why?
For everybody else this is way, way worse than Iraq in 2003. "Freedom fries" seems cute in hindsight.
Iraq was the gift that kept on giving with ISIS. Now you're asking countries who saw how that went to sign on to an even bigger blunder (from their perspective)?
And for what? So that in 20 years, another POTUS can just say their troops were standing around doing nothing?
I don't think Americans understand the depth of anger in Europe right now. And quite a few probably don't care or even think Europe deserves it. Fair enough. But it's quite frankly audacious to go from "We're invading Greenland," in January, to, "Y'all need to suit up and join us in Iran."
Europe has its hands full anyway supporting Ukraine, the war that America seems to have forgotten.
