Don’t Scapegoat China for Killing the INF Treaty. Ask it to Join.

, China project manager and senior analyst

September 23, 2016: Chinese UN Representative Liu Jieyi votes in favor of a UN Security Council resolution on the 20th anniversary of the signing of the Comprehensive Test Ban Treaty (CTBT) urging all parties to push for the treaty’s entry into force.

The Trump administration recently announced it intends to walk away from an important agreement that reduces the risk of nuclear war—the INF Treaty. US officials said concerns about China were an important factor in deciding to scrap a nuclear arms control pact intended to last in perpetuity. But there is no evidence the Trump administration consulted Chinese leaders about its plans to withdraw or the concerns that supposedly made it necessary. Read more >

New Analysis: US Missile Defense Tests Lack Realistic Decoys

, co-director and senior scientist

Rumor has it that the administration’s Missile Defense Review (MDR) may finally be released this week. As policy makers discuss its recommendations and consider expanding US missile defenses in various ways, they should have a realistic view of the capability of these systems—and their limitations.

There have been 18 intercept flight tests of the Ground-based Missile Defense (GMD) system through 2018. Contrary to some claims, these tests have not demonstrated that the missile defense system would be successful in intercepting incoming warheads under realistic conditions. Read more >

The Long-Overdue Missile Defense Review Expected (Again) This Week

, Washington representative and senior analyst

Where’s the Trump administration’s hugely delayed Missile Defense Review? The latest rumor is that it will be released this coming Thursday, and that seems plausible (but I wouldn’t hold your breath).

The review was congressionally mandated in the FY17 National Defense Authorization Act (NDAA) and was originally expected in late 2017. Then it was expected around the February 2018 release of the administration’s Nuclear Posture Review. After that, it was expected in May. Now, it is more than a year late, and what it says remains a mystery. Read more >

No, Space-Based Missile Defense Will Not Cost Only $20 Billion. (Spoiler: That’s only the launch costs.)

, senior scientist

Space-based missile defense is a terrible idea. It is expensive and straightforwardly defeated, and it is dangerous and destabilizing. (If you haven’t watched it, please do take a look at this video and web feature UCS just produced. It helps to see these arguments visually.)

But knowledgeable people say it’s not so expensive!

At a recent event hosted by the Missile Defense Advocacy, Under Secretary of Defense for Research and Engineering Mike Griffin calculated the cost to “put up” an interceptor layer. Given how Griffin talked about it, you may be forgiven for thinking he means this is the full cost of a space-based missile defense system—rather than just the cost of launching the interceptors into space.

How to Think about Space-Based Missile Defense

, co-director and senior scientist

UPDATE: In September 2018, UCS released an animated feature and video that explains how space-based missile defense works. Check it out here.

The idea of space-based missile defense system has been around for more than 30 years. There are at least two reasons for its continuing appeal. Read More
