When the U.S. Department of Defense released its latest cyber strategy last week, it laid more than just another brick in the edifice of cybersecurity that the government has been building for decades. Coming just a few weeks after President Barack Obama’s Executive Order setting out a policy framework for sanctioning malicious cyber actors, the new strategy marks a significant evolution in Washington’s understanding and approach to providing security in the digital age. That’s because it comes with a warning to potential adversaries: The United States will no longer only be reactive in its cyber defenses, as the Pentagon will […]

This past weekend, I had the privilege of taking part in the Harvard Extension School’s Crisis Game, a Cold War-era nuclear simulation involving some 30 graduate students and led by my colleague Tom Nichols. What was fascinating to observe was how even the prospect of a theoretical nuclear exchange was still capable of forcing a high degree of seriousness and focus among the participants, as various courses of action were debated and evaluated. Indeed, some of the participants themselves raised the question of whether U.S. national security policy today lacks the gravitas it appeared to have 30 years ago, particularly […]

U.S. Secretary of State John Kerry addresses the 2015 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), U.N. headquarters, New York, April 27, 2015 (U.N. photo by Loey Felipe).

The monthlong 2015 review conference of the Non-Proliferation Treaty (NPT), which began yesterday, will put a spotlight on a number of priority issues on the nonproliferation agenda. Of these, the potential deal between Iran and the P5+1—the United States, United Kingdom, France, Russia, China and Germany—on Tehran’s nuclear program, which would bring Iran back into compliance with its NPT obligations, is likely to attract the most attention. However, the current arms control stalemate among the U.S., Russia and China, which has endured since the previous NPT review conference in 2010, will also shape the conference’s outcome. This stalemate results from […]

When U.S. President Barack Obama announced his strategy for countering the so-called Islamic State (IS) last September, it was met with an immediate volley of criticism, most of it asserting that the president’s approach was too timid. Incensed by IS’ horrors, the critics called for large-scale American military action. Sen. Ted Cruz, for instance, demanded that the Obama administration “destroy” IS within 90 days. When told by Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, that this was impossible, Cruz issued a press release saying the general was wrong. Now that the 2016 presidential race has kicked off, […]

Meeting of NATO defense ministers, NATO Headquarters, Brussels, Belgium, Feb. 5, 2015 (NATO photo).

Whether it was the deaths in the Mediterranean Sea of hundreds of migrants and asylum-seekers desperate to enter European territory or the latest atrocities carried out by the Islamic State in their Libyan enclave, this week’s headlines could not have come at a worse time for the leadership of the North Atlantic alliance. Over the past year, NATO finally seemed on the verge of rediscovering a common purpose after two decades of trying out for different roles—a return to its original task of putting a brake on the westward spread of Russian influence and control from the Eurasian core into […]

U.S. Defense Secretary Ashton Carter meets with Japanese Prime Minister Shinzo Abe, Tokyo, April 8, 2015 (DoD photo by U.S. Navy Petty Officer 2nd Class Sean Hurt).

Earlier this month, Ashton Carter concluded his first visit to the Asia-Pacific region since becoming U.S. secretary of defense. In Japan and South Korea, Carter delivered several speeches underscoring the region’s importance and explaining the logic of U.S. President Barack Obama’s “pivot” to Asia. Carter will return to visit Singapore and India in a few weeks, a sign of how pivotal a player he has quickly become in the administration’s policy of “rebalancing” America’s strategic priorities toward the region. Carter’s recent trip, which began April 7 and ended April 12, aimed to reassure the two countries he visited, Japan and […]

For American defense professionals, the 1990s now seem like a distant dream. The United States was fresh off a stunning military victory over Iraqi dictator Saddam Hussein’s forces in Kuwait. The Soviet Union, long Washington’s bête noire, had crumbled. The American economy was robust, churning out important technological innovations one after another. In these halcyon times, U.S. military leaders and defense officials predicted that they would master what they called the “revolution in military affairs,” thereby attaining battlefield superiority over every possible enemy. Since the U.S. would be able to impose its will on opponents, there was little need to […]

U.S. President Barack Obama and Cuban President Raul Castro shake hands at the Summit of the Americas in Panama City, Panama, April 11, 2015 (AP photo by Pablo Martinez Monsivais).

One of the most salient criticisms of U.S. President Barack Obama’s recent overtures to Iran and Cuba is that neither country, as a condition for engagement, has agreed to undertake fundamental reforms of their internal political systems or alter the general direction of their foreign policies. Indeed, the leaders of both countries have claimed victory in defying those types of demands. In theory, this need not be a setback. When Richard Nixon traveled to China in 1972, Mao Zedong did not repudiate his ideology, release any political prisoners or make any commitment to pursuing liberal political or economic reforms. Nixon, […]

U.S. President Barack Obama speaks at Howard University in Washington, Tuesday, April 7, 2015 (AP photo by Pablo Martinez Monsivais).

Several events in the past month have raised the question of whether the United States has entered the first stages of its decline in the global arena. Of them, the framework agreement reached between the P5+1 powers—the U.S., U.K., France, Germany, Russia and China—and Iran in Switzerland last week has received the most scrutiny. The U.S. entered diplomatic efforts with the stated goal of seeing Iran’s capabilities to enrich uranium completely dismantled—but ended up accepting Iran’s right to preserve, albeit under rigid supervision, a good deal of its nuclear infrastructure. While the Iran talks have dominated the headlines, there have […]

On April 1, U.S. President Barack Obama signed an executive order expanding Washington’s ability to deter cyberattacks, by empowering the government to apply financial sanctions on hackers and companies overseas that benefit from cyber-espionage. The directive authorizes the secretary of the treasury, in consultation with the attorney general and secretary of state, to impose sanctions on individuals and entities that he determines are responsible for, or complicit in, malicious cyber-enabled activities that may constitute a threat to U.S. national security, foreign policy, economic health or financial stability. The measure was no April Fool’s Day joke. Indeed, it reflects a move […]

U.S. President Barack Obama walks to the Rose Garden of the White House in Washington, to speak about the breakthrough in the Iranian nuclear talks, April 2, 2015 (AP photo by Pablo Martinez Monsivais).

Is U.S. President Barack Obama the last great Cold War statesman? Obama aspired to be a transformational figure in U.S. politics. Yet when it comes to international affairs, he often harks back to America’s old confrontation with the Soviet Union. Justifying the last-minute push for a nuclear deal with Iran last week, he borrowed a line from former President John F. Kennedy: “Let us never negotiate out of fear, but let us never fear to negotiate.” After Iran agreed to the framework deal Thursday, Obama returned to the history books. Speaking at the White House, he quoted Kennedy again and […]

In January 2017, a new U.S. president will move into the White House. He or she will immediately instruct the National Security Council to assess American national security strategy and provide policy options, particularly for key regions and issues. In all likelihood, no assessment will be more complex and important than the one dealing with the Middle East. After the end of the Cold War, U.S. strategy in the Middle East focused on promoting stability largely by supporting like-minded regional states. While nominally opposed to the more nefarious dictators in the region, before 2003 the U.S. did not do much […]

U.S. President Barack Obama’s efforts to secure an agreement with Iran over its nuclear program have exposed rifts with America’s long-standing Middle Eastern partners, including Saudi Arabia, Egypt and Israel. While these three countries share important security interests with Washington, they are by no means fully aligned with the preferred American vision for the region. For its part, Saudi Arabia has always feared Iranian hegemony in the Middle East, no matter who sits in power in Tehran. Riyadh was no more supportive of Iranian claims to regional leadership, and in fact opposed efforts to enshrine Iran as America’s Middle Eastern […]
