It seems like one reason why Russia’s actions in Crimea appear so jarring and brazen is that it’s a form of warfare that was once common but rarely take place anymore. Russia may not formally annex Crimea – it seems more likely that the territory will declare independence under heavy Russian influence – but it has essentially invaded another country to lob off a piece of territory that was, despite longstanding nationalist sentiment, an undisputed part of Ukraine.

Stunned by Russia's swift move into the autonomous province of Crimea and the Russian parliament's endorsement of that brazen action, the United States called on Moscow to withdraw its forces from the region and "refrain from any interference elsewhere in Ukraine." Speaking by phone with Russian President Vladimir Putin for the first time since this crisis escalated, President Obama expressed concern over "Russia's clear violation of Ukrainian sovereignty and territorial integrity," according to a White House statement.

At a recent series of events in Beijing hosted by the Berggruen Institute, I was asked to speak about social media and the potential harm and good associated with it. My view is pretty straightforward -- I believe that social media is a tool of liberation and empowerment. That may seem fairly audacious when a good portion of the Western world is using Facebook and Twitter to post pictures of what they had for dinner or take quizzes on what TV character they may be. 

It had been years since a crowd this big gathered for an event like this. Hundreds filled Khartoum International Community School's amphitheatre, a posh school for children of the city's elite, some even crammed on its stairways. A white screen slowly descended and after short introductions, a film began rolling.

If Brazil is not for beginners, as the saying goes, then Venezuela isn't, either. But as far as the two countries' recent protest experiences go, they have a few interesting elements in common. At first glance, the countries seem quite different: Venezuela is deeply and bitterly politically polarized, with shortages of basic food staples and goods, rising inflation, spiraling crime rates, and what some say is a breakdown of institutions.

Sustained anti-government rallies in Thailand, Ukraine and Venezuela have captured the attention of millions. But large pro-democracy demonstrations in Burkina Faso last month largely escaped the Western media’s radar. Since January, tensions have flared between the West African country’s authoritarian government and the impoverished masses yearning for democratic reforms. Depending on how developments unfold, the protests in Burkina Faso could serve as a catalyst for further uprisings in the region.

As much of the world’s media continues to focus on the politics of the 2014 Sochi Winter Olympics and the continued violent protests in the Ukraine, another country closer to home threatens to descend into civil war. Street demonstrations throughout Venezuela, now entering their second week, have turned a country already suffering from high rates of violent crime and murders into a battleground.

The US State Department has expelled three Venezuelan diplomats in response to last week's expulsion of three consular officials from Caracas. Jen Psaki, the department's spokeswoman, said on Tuesday that First Secretary Ignacio Luis Cajal Avalos, First Secretary Victor Manuel Pisani Azpurua, and Second Secretary Marcos Jose Garcia Figueredo, have 48 hours to leave the US.
