Ukrainian President Poroshenko is provoking Putin in the hopes of drawing Western attention. It’s a risky move.

German Finance Minister Wolfgang Schäuble accused Putin of emulating Hitler’s tactics in the Crimea. He has a point. Putin is no Hitler, but he’s using the same playbook.

Putin has made it increasingly clear that he intends to respond to Western sanctions by frustrating nuclear talks with Iran. Obama may face the choice he’s worked hardest to avoid: attack Iran, or allow it to go nuclear.

Russia’s Deputy Foreign Minister is threatening to alter Russia’s stance on Iran if the West doesn’t come around on Crimea. This is Obama’s nightmare scenario.
