How does Russian determine its interest? Right now, it’s determined based on what the ex-KGB oligarchy says. As a non-free nation, that’s a dubious affirmation of interests.
When I say "Russian interest" the implication is their perceived interest. And the "they" refers to the people in charge, as it always has.
Tell me, did the United States react to the attack in Benghazi in Obama's perception of best interest, or in a manner that would have been consistent with the majority view of Americans?
Putin wants Russia to be powerful and more dominant. For himself, he wants glory and the respect of his people.
What does Obama want for the United States, and what does he want personally?
