We responded when the Germans even suggested to Mexico they would help them take back the Southwestern US, even though Mexico had no intention of doing so, but that was enough for us to declare war on Germany.
Do you really believe the U.S. would respond Militarily?
If using the same formula you gave, the U.S. should have invaded Mexico decades ago.
Narco State?
Allowing invaders into the U.S. to pass through?
I don’t give a damn what Russian KGB says was going on in Ukraine that triggered their invasion.
Nazis………..Corruption……….Money Laundering………whatever.
We have those exact things going on here.
Until we are better than Russian standards for invasions, your argument fails, as does Putin’s.
Now go invade Idaho and DeNazify them.
