Joint Chiefs of Staff Chairman Martin Dempsey's acknowledgment this week that Iran "is a threat to U.S. national security in many ways," and not just in its pursuit of nuclear weapons, is both welcome and timely.

In highlighting Iran's nuclear pursuit, U.S. policymakers and pundits have cast insufficient light on Tehran's other activities in the region and beyond that dog U.S. security interests and make its potential nuclear capacity so frightening.

Last week, Argentine state prosecutor Alberto Nisman dropped a bombshell when he issued his long-awaited indictment in the 1994 bombing of the Argentine Israel Mutual Association (AMIA) in Buenos Aires. The 502-page report pins the blame for the attack -- which killed 85 and wounded hundreds more in what experts call Latin America's 9/11 -- squarely on the Islamic Republic of Iran. In doing so, it provides a timely reminder that Iran's radical regime is active in the Western Hemisphere and that its presence here is far broader than is commonly understood.

President Obama's counter-terrorism strategy, which he unveiled last week in a high-profile speech at the National Defense University, is less off-base than incomplete, reflecting his effort to limit the scope of the problem and the requirements of the response in ways that will prove inadequate to the challenge.

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.

With international pressure over its nuclear program mounting, and the recent collapse of its latest round of negotiations with the West, this might seem like a strange time for Iran to pick a fight with its neighbors. Yet on at least one front, that is exactly what it appears to be doing. Recent days have seen a marked downturn in the already-troubled relationship between the Islamic Republic and Azerbaijan, its neighbor to the northwest.

The passing of Hugo Chavez last week shouldn't have come as much of a surprise to most observers. The death watch for the long serving Venezuelan strongman had been in effect since at least mid-2011, when he confirmed longstanding rumors by publicly announcing that he was being treated for an aggressive form of cancer.

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."

...or does it?;
With an eye towards election, a new order of battle

Iran's presidential election may still be some four months away, but the political machinations have already begun. Last week, Iran's Council of Guardians, the powerful governmental oversight body tasked with interpreting the country's constitution, passed a new law imposing additional curbs on the electoral process within the Islamic Republic—and adding a new layer of bureaucracy to its already-convoluted political process.

A significant shift is underway in U.S. defense posture. Over the past year, the Obama administration has carried out a public pivot in strategic focus toward the Asia Pacific theater. The reorientation has been driven in large part by concerns over China’s “peaceful” (or not so peaceful) rise to regional prominence—and by an effort to exploit the opportunities that have been created by it. Widespread regional unease over China’s growing footprint among Asian countries has paved the way for stronger relationships between Asia and the United States, as well as a growing willingness to partner with Washington on matters of regional security and politics.

Today, the United States confronts no shortage of strategic challenges in the Middle East. Initial optimism about democratic change among the countries of the “Arab Spring” has given way to deep apprehension over the ascendance of Islamist forces in places like Egypt and Libya. The post-Saddam government of Iraqi Prime Minister Nouri al-Maliki remains fragile and unstable, riven by sectarian divisions and propelled by divisive power politics. And al-Qaeda, although down in the wake of the May 2011 killing of Osama bin Laden, is decidedly not out, as frequent bombings in Iraq and mounting unrest in Yemen underscore.
