In this March 21, 2014, photo, Russian President Vladimir Putin signs bills making Crimea part of Russia in the Kremlin in Moscow. U.S. sanctions against a Russian bank and the Kremlin’s inner circle have pinched Moscow, but if the goal is to get Putin to roll his forces out of Crimea or prevent him from doing any more land grabs, their effectiveness remains in doubt. Putin has mocked the punitive steps President Barack Obama has taken so far in their post-Cold War game of chess _ or chicken. (AP Photo/Sergei Chirikov, Pool)
