Chomsky does accuse the US government of not wanting a democratic government in Egypt, but doesn't actually blame them for the failure of the Morsi government. Instead he blames his friends in the left Liberal movement of Egypt for supporting the Military coup.

As for Obama fudging the question of whether it was a coup, that's exactly the useless after the fact hand-wringing I'm talking about. At that point the coup was a done deal.

It may even be true that western leaders prefer to deal with Middle Eastern autocrats, but (a) when given the opportunity that's not what they set up in Iraq. And (b) they don't actually get to decide who rules any Arab countries anyway. Even in Iraq which they conquered, because they handed that decision over to the electorate.
