Americans were complicit because it didn't (immediately and viscerally) effect them, just like Russians have been so far. If it effects them enough they'll stop working.

> Punishing civilians for the actions of its government

With few exceptions, governments serve the people under them. Pray tell, How popular is Putin in Russia right now?
