This is fecking absurd. Saying that the US is the aggressor here is as stupid as saying that Russia was the aggressor in the Iraq war. It makes no sense at all.
Neither does the parallelism that both sides are as bad as each other, or whatever the feck insane posts I've read in this thread during the day.
In this conflict, there is only one aggressor, called Russia, and it is to be blamed for approximately 100% of it. There are no two sides here, there are no multiple factors to be blamed, etc etc.

It is the same as in the Iraq war where all the blame was in the US. Here, all the blame is in Russia who are going to invade a country with which they have deals that they won't invade it. All to appease a brutal dictator.
