Michael McFaul

Michael McFaul, who sat in on meetings between Putin and Obama, warns that the Russian president "doesn't meet just for the sake of a meeting; he seeks to advance Russian interests."

Michael McFaul, ambassador to Russia from January 2012 to February 2014, says, "I've never seen [Putin] devote a speech to the necessity of reuniting Crimea with Russia. That came only recently."
