Ever since last month’s bombings at the Boston Marathon, speculation has abounded as to what led the perpetrators — suspected to be ethnic Chechens 26-year-old Tamerlan Tsarnaev and his 19-year-old brother, Dzhokhar — to carry out the most significant act of terrorism on U.S. soil since Sept. 11, 2001. By all accounts, both were largely homegrown radicals who received inspiration, and perhaps even dangerous instruction, from jihadist elements in the United States and abroad. The roots of the Tsarnaevs’ militancy can be traced back at least in part to Russia’s own troubled “war on terrorism” — a struggle that Moscow, more than two decades after the Soviet collapse, is in real danger of losing.

These days, American policy toward the Middle East tends to be dominated by two regional crises.

The first is the long-running showdown with Iran over its nuclear program. Despite mounting Western financial pressure, the Islamic republic shows no signs of changing course. To the contrary, Iran’s leaders have defiantly tightened their fiscal belts and redoubled their efforts to cross the nuclear Rubicon. Meanwhile, negotiations between Tehran and the West have concluded predictably, without any tangible progress on bringing the Iranian regime’s nuclear ambitions to heel.

The apprehension of Dzhokhar Tsarnaev ends a five day reign of terror in the Boston area. Taking him alive allows authorities the opportunity to find answers to critical questions surrounding the deadly April 15 Boston marathon bombing. Most important of this is, why did Dzhokhar and his brother Tamarlan allegedly do it?

Secretary of State John Kerry made news recently by referring to the venue of the latest nuclear talks with Iran as the fictional country of "Kyrzakhstan." That off-the-cuff comment was a telling indicator of the general lack of concern for Central Asia that prevails in official Washington.

Suddenly, it's springtime for diplomacy with Iran once again. After a year that saw a dramatic escalation of economic pressure against the Islamic Republic, the Obama administration and its allies are now once again talking to Tehran. Yesterday, negotiations concluded in Almaty, Kazakhstan on the latest round of multilateral diplomacy aimed at bringing Iran's nuclear ambitions to heel. Additional talks are now set for April, to be held once again in Kazakhstan.

During Secretary of State John Kerry's listening tour of the Middle East, one troubling regional issue might go unspoken: the possibility that Iran already has nuclear weapons capability.

Just what will it take to bring Iran’s nuclear ambitions to heel? The past year has seen a dramatic expansion of economic pressure against the Iranian regime by the United States and Europe, all with a single-minded purpose: to ratchet up the costs to Iran of its stubborn atomic endeavor.

In his State of the Union Address, President Obama pledged that "America will continue to lead the effort to prevent the spread of the world's most dangerous weapons."
