The rest of the world wouldn't do anything about it either, IMO. Just like they're doing for Ukraine now.
Also much more people have been to Italy,or at least know the country and it's culture compared to Ukraine. So the Fallout in Public Opinion would be way worse. China would also be salivating at an Opportunity to isolate the US, and that would be one presented on a silver platter
I don't think you can impose enough diplomatic sanctions on America to make us care, and certainly not enough to make up for deleting Italy.
Response was: Yes, Italy could choose to do so. However, American would probably delete Italy if Italy made that choice.
So France would not be looking at the US deleting Italy for no reason.
You really think the French are going to sacrifice themselves to avenge the Italians?
In the normal state of human affairs, being a pariah doesn't matter as long as your goals get done
