Relations between the United States and Russia have become increasingly frosty, as issues like temporary asylum for NSA leaker Edward Snowden and Russia’s new anti-gay “propaganda” law have helped drive a wedge between the two countries and its leaders. But perhaps the biggest issue overshadowing this week’s G-20 summit in St. Petersburg has been Syria. Russian President Vladimir Putin maintains that any military strikes in Syria must first be approved by the United Nations Security Council, but U.S. Ambassador to the United Nations Samantha Power shared a different view Thursday, saying that “we have seen nothing in President Putin’s comments that suggest that there is an available path forward at the Security Council.” We talk with the Carnegie Endowment’s Andrew Weiss about what’s ahead for U.S-Russia relations.
