The 50-year-old Revolutionary Armed Forces of Colombia (FARC), once considered the best-funded insurgency in the world, is at its smallest and most vulnerable state in decades, due in part to a CIA covert action program that has helped Colombian forces kill at least two dozen rebel leaders, according to interviews with more than 30 former and current U.S. and Colombian officials.

US President Barack Obama has warned South Sudan that Washington and its allies would cut aid to the country over any attempted military coup, amid growing fears of civil war.

Cuban President Raul Castro on Saturday called on the United States to establish civilized relations with his country, recognizing a new tone in bilateral talks on secondary issues while reiterating that the country's political and economic system were non-negotiable. The United States and Cuba have appeared more positive of late as talks around immigration, postal services, disaster prevention and other security issues have taken place, with officials from both countries cautiously welcoming each other's pragmatism and seriousness in interviews with Reuters.

A hot topic these days in D.C. is the quest for what is quickly becoming the foreign policy holy grail — a U.S. foreign policy strategy towards the People’s Republic of China. The quest in many respects makes sense. After the declaration of a “pivot” to Asia, many in America’s foreign policy community expected a major push by the Obama Administration to clearly define some sort of strategy towards Beijing incorporating a number of broad areas of importance — defense, economic, and cultural interactions.

Thailand’s main opposition Democrat Party said Saturday that it would boycott February’s general election, deepening a weeks-long political crisis over protesters’ efforts to oust the government and force political reforms.
