We're leaving. No, you're not. That's where the crisis in Ukraine stood Thursday after lawmakers in Crimea voted in favor of leaving the country for Russia and putting it to a regional vote in 10 days. This act drew widespread condemnation, with Ukrainian interim Prime Minister Arseniy Yatsenyuk calling such a referendum "an illegitimate decision." "Crimea was, is and will be an integral part of Ukraine," he said. It was a sentiment echoed by several world leaders, who called the scheduled vote and possible pullout violations of Ukrainian and international law. "Any discussion about the future of Ukraine must include the legitimate government of Ukraine," said U.S. President Barack Obama. "In 2014, we are well beyond the days when borders can be redrawn over the heads of democratic leaders."
