Perhaps. But if the Mexican government decided to allow the autonomous region of Southern California to fire mortars into Nevada, I wouldn't blame the people of Nevada if they moved in to put a stop to it.
This is a situation that has been slowly engineered by the Russians over a decade. Their active support (in training, arming, and funding) terrorists eliminates any argument Russia might have that they are the wronged party here.
I haven't exactly been privy to all that's been going on there in recent years/months.
That is probably the biggest problem with this conflict. The western media has almost completely ignored this problem which has been actively brewing since the late 1990s. When proof of Russian support for the various terrorist activities (car bombs, destruction of infrastructure, assassinations, etc.) are shown by the Georgians (they successfully captured some saboteurs a few years back), it gets ignored in the western media as not being "newsworthy".
You might have also added that the Mexican gov’t extended citizenship to the Californians then armed them to lob the mortar shells into Nevada claiming the Californians turned Mexicans ... oh, never mind. What a mess this is, especially with US so energy dependent.
