Obama gambled that U.S. power would trump Russia's interests in Ukraine. He was wrong.
The Obama administration was clearly taken by surprise when Russia decided to seize Crimea by force. The real question, however, is why Obama and his advisors thought the United States and the European Union could help engineer the ouster of a democratically elected and pro-Russian leader in Ukraine and expect Vladimir Putin to go along with it? This remarkable combination of hubris and naiveté is even more striking when one considers that Washington has few, if any, options to counter Putin's move.
