Good thing russians are not mad enough to shoot down american planes because they know the state of insanity america is in right now. If they start shooting down the air force the crazies in the pentagon get the chance to unite a divided america for another great war, not good.
By the way russia is geopolitically on the retreat, it simply cannot fight NATO if it is not on its own territory. but don't worry, as long as there is putin, he will play it smart.
