This is naive. No other country would dare do this to the US because the US would simply rain literal hellfire upon them.

Your mistake is in equating the US to other countries. You cannot. It is a superpower.

When other countries act hostile to the US, it can simply ignore their sovereignty at a whim, and this is a huge benefit to living in US.

Is it unfair? Sure. Who cares?

Israel did that in Argentina with Adolf Eichmann, and the US celebrated it.

That other country will quickly learn why America doesn't have free healthcare ;)

If Trump successfully stole the election in 2021, I'm sure there would have been many Americans who would be happy for Canada or England or France to capture him and put him on trial..
