Russian Deputy Prime Minister Dmitry Rogozin reacted quickly on Twitter to the news that he was among seven Russian and several Ukranian and Crimean officials sanctioned by President Obama on Monday.

Rogozin has a reputation for using social media to engage in combative tweaking of Western officials, but his most recent tweets give a good impression of just how scared Russian officials are of Obama's latest moves to convince Moscow that it should reverse its takeover of Crimea.
