Officially, the U.S. is accusing Russia of "crimes against humanity". It's the old standby when the military industrial complex needs some revenue to pay off more Pentagon officials and realize a profit. It usually brings the ignorant into thinking we need to spend billions punishing the supposed perpetrators, when the entire problem can be resolved with a few arrests of the U.S. criminals involved in the subterfuge.
So, here we go again. We send the young off to get their asses blown off, make room for the millions of aliens slinking into the United States, and the costs of everything will become obscene so trillions can be plundered from the private sector. Amazingly enough, the vast majority of U.S. citizens are too ignorant to realize they're being played as dupes, but as P.T. Barnum said: "There's a sucker born every minute".
