This piece originally appeared in Politico. Effective security cooperation means responsibilities for both sides. The Mexican government has the bulk of the work when it comes to fighting the drug runners threatening their country. They look to be taking this seriously. U.S. policymakers need to match that seriousness: both by following through on past commitments and by laying the groundwork for a successful bilateral relationship with Mexico in the future.

A new memo I co-authored defends Obama’s nuclear doctrine and outlines the security-focused aspects of the Nuclear Security Summit, the Nuclear Posture Review, and the New START treaty with Russia: From the introduction: The Obama administration’s nuclear doctrine, defined by New START, the Nuclear Security Summit, and the Nuclear Posture Review, is a responsible approach to improving US security. It builds on a long, bipartisan history of seeking to contain and reduce the prevalence of nuclear weapons around the world. It properly places the threat of nuclear terrorism as a top security...

Last year -- in stories from the Wall Street Journal to the New York Times -- we saw the emergence of a narrative that Palestinians in the West Bank are living through an economic miracle. One very important missing piece of this puzzling story is Gaza and its desperate state of affairs. While this may seem like a small story in the context of much larger conflict, the economic well-being of West Bank residents has taken on increasing importance as leaders on both sides of the Israeli-Palestinian divide are banking on economic growth as a route to a viable two-state solution, while simultaneously ignoring the situation in Gaza.

It’s a strange time for national security politics.

With all that, the only thing conservatives want to talk about on national security is whether terrorists should be arrested, held, and tried in the criminal civilian court system. This should be a simple legal question. If a terrorist breaks a US...

There’s no denying it: Iran-related security challenges are extremely complex, and any progress will require time, patience, and determination. Anyone who argues that there is a quick fix to long-simmering disagreements with Iran is at best uninformed and at worst willfully foolish. The Obama administration seems to understand these fundamental facts and has continued with its dual-track policy of engagement and pressure even in the face of critics who portray engagement as weak or naïve. In a memo I co-authored for Third Way, we argue that engagement has shown concrete results and continues to...
