Three years ago this summer, Egyptians took to the streets en masse to vent their frustration at the government of then president Mohamed Morsi. The source of their discontent was the widespread economic stagnation and ideologically driven policies that came to punctuate Morsi's Muslim Brotherhood-dominated government. The result was nothing short of a counterrevolution, as Morsi was ousted by the country's powerful military in an almost-coup led by his then minister of defense, Gen. Abdel Fattah el-Sisi. 

Last month, U.S. Defense Secretary Ashton Carter reflected on the remarkable progress he and his Indian counterpart, Manohar Parrikar, have overseen in bilateral defense ties over the last two years. With his gift for memorable analogies, Carter insisted the budding Indo-U.S. defense partnership was built atop two “important handshakes.” One was a “technological handshake,” a reference to the rapid growth in arms sales, co-development, and technology-sharing. A companion piece to follow this article will explore the technological handshake in greater detail, and the opportunities and challenges that lie ahead.

The nuclear threat from North Korea continues to grow, despite numerous strong statements of concern from the United States. But Pyongyang knows that talk is cheap. The more powerful message from American inaction is: keep building. 

"We shall proceed with reform and opening up without hesitation," China's President Xi Jinping told his country's top leaders in August 2014 during a symposium marking the 100th anniversary of the birth of former leader Deng Xiaoping. At the time, this pledge appeared sincere. Since taking office in March 2013, Mr. Xi had consistently advocated a reform agenda intended to continue the economic restructuring and national revitalization that Deng had started in 1978. Now, two years later, and despite his consolidation of power, Mr. Xi's reforms are mired in a morass of bureaucratic hurdles and official foot dragging. 

Greater cooperation with Russia in the struggle to defeat the Islamic State terrorist group (ISIS) and other extremist elements in the Muslim World is now being urged by a number of prominent Americans. Russia and America both have a problem with Islamists, goes the argument, so we should work together to defeat the common enemy. 

In Washington, conventional wisdom has long held that Iran's presence south of the U.S. border constitutes little more than an axis of annoyance. In this telling, Iran's activities in Central and South America - from numerous commercial and trade deals with various nations to the establishment of cultural centers throughout the region - are disorganized, opportunistic, and ultimately of little consequence. 

Years from now, historians are sure to view the nuclear deal concluded last year between Iran and the P5+1 powers - the U.S., U.K., Russia, China, France and Germany - as the greatest foreign policy achievement of President Obama's second term. But it is far less clear that they will see the agreement as having advanced America's strategic interests. 

On a hot rainy day in August 2013, a group of young Colombians were celebrating the completion of a playground project in the village of Villarrica, Tolima. The project was funded by a nonprofit, Fundación ECCO, which I founded to encourage youths in rural areas affected by violence to develop leadership skills and engage in the democratic process.

Does anyone remember Mahmoud Ahmadinejad? Until recently, the Islamic radical and former military officer who served as Iran's sixth president could be considered something of a political footnote. 

The United States was humiliated this week when the USS Nitze came under simulated attack by four Iranian missile and torpedo-equipped speedboats in international waters. Despite American warnings, radio calls, flares and foghorns, two of the boats came within a few hundred yards of the Nitze. Iran is harassing American naval warships in the Persian Gulf while Washington refuses to acknowledge Iranian threats for reasons that are both political and practical.
