there is hypocrisy. it is a point we've made many times. the us really lost its moral standing during the iraq war. the us' sense of its own exceptionalism is a problem in the world.
but that doesn't make what putin did okay. if putin thinks the us was wrong, he can't demonstrate russian virtue by doing something wrong himself.
as a separate matter, yes, the us also did something iniquitous. but right now, pooty-poot, you are on the hot seat.
