I get that collapse is a slow ongoing process but when the history books are written, what do you think will be considered the US' own Battle of Ravenna? What will occur that historians can point to it and say, "this was the effective end of the American empire." ?
As long as there is no real "punishment" from the international community (lol), this doesn't mean much. The US military is big enough that it can do anything on its own. Warhawks just wanted more nations for optics.
