Topless demonstrators in Ukraine are part of the self-defined “sextremist” Femen group – radical women protesting the Russian invasion of Crimea. Femen is a stark example of frontline femmes who use their bodies and their voices to fight status quo corruption, war and a political oligarchy.

As tensions spiral between Russia and the West over the crisis in Ukraine, the Obama administration is denouncing Moscow's imposition of new restrictions on independent Russian media. The State Department on Friday said it was "deeply troubled" by dramatic new curbs on press freedom that it said make it easier for the government to spread "patently false" information.

Roughly seven in 10 Americans view Russia as a threat to the United States, a new poll released Friday shows, the highest percentage since the break-up of the Soviet Union. Sixty-nine percent say Russia presents a "very" or "moderately" serious threat to America -- up 25 percentage points since April 2012, according to the CNN/ORC International poll.

Chancellor Angela Merkel has issued an ultimatum to Russia over what she called its annexation of Crimea: Back down or face strong measures from the European Union. Accusing Moscow of acting by the “law of the jungle” in an address to parliament on Thursday, Merkel said Russian President Vladimir Putin’s actions are a clear breach of international law and threatened full-fledged economic sanctions.

It's a good time to have friends in Eastern Europe.

Members of the Russian parliament have written to FIFA asking it to consider excluding Jurgen Klinsmann’s USA team from the 2014 World Cup finals in Brazil. Alexander Sidyakin and Michael Markelov, two members of the Duma, addressed their concern about the “U.S.’s military aggression against several sovereign states” and named Yugoslavia, Iraq, Libya and Syria among those suffering from U.S. aggression.

Recent developments in Ukraine have been nothing less than astonishing -- and that's just as true of seasoned observers of Eastern Europe as it is of everyone else. Russia's bold and illegal military intervention issues a startling challenge not just to Ukrainian independence but also to the very foundations of the post-war liberal order.
