The US ambassador to Russia has announced that he is stepping down after two turbulent years in Moscow. Michael McFaul is considered the architect of President Barack Obama's effort to reset relations with Russia.
McFaul points to many successes in US-Russian relations, including the negotiation of a new strategic arms treaty and cooperation on the NATO-led military campaign in Afghanistan. But his tenure also has brought disappointments in the face of the rising anti-Americanism in Russia that accompanied Vladimir Putin's return to the presidency. (AP)
