If you ever wanted to start a major war with the US, now is the time. Our forces have been reduced. Military morale has to be at an all time low, since the Democrats have moved all their social programs into the only Govt organization that worked right. I'd bet most of the "hardline" patriotic, high ranking officers have been forced out - because of the line in the oath, "against all enemies, foreign or domestic". Add to that sad commentary the like of patriotism in our country today, and you've got the perfect storm.
Seriously, if Russia landed troops on the shores of North Carolina, how many California's do you think would pick up a weapon to help fight them? Or, if they landed in Cal, how many New Yorkers? The US is sitting here, ripe for the taking. To me, this country is literally FUBAR.
