The Arms Control Association is an "exceptional organization that effectively addresses pressing national and international challenges with an impact that is disproportionate to its small size."

Although plans for expanding U.S. strategic missile defenses focus on the Iranian ICBM threat, that threat is not emerging as was previously predicted.  Iran conducted no long-range ballistic missile tests in 2012 and has not flown even the larger space launch vehicle that it displayed two years ago, which could have helped advance ICBM technology.  Moreover, Tehran has still not decided to build nuclear weapons and continues to focus on short- and medium-range rather than longer-range ballistic missiles.

It is, therefore, time to adapt U.S. missile defense plans accordingly by suspending the fourth phase of the European Phased Adaptive Approach. Doing so would remove an obstacle to negotiating further reductions in the strategic forces of Russia - the only country that poses an unambiguous existential threat to the United States.
