Michael Levi talks with Robert McMahon about the deadlock in climate change negotiations and argues that the world urgently needs a "Plan B" for Copenhagen.
The Copenhagen conference won't solve the problem of climate change once and for all. Rather than aiming for a broad international treaty, negotiators should strengthen existing national policies and seek targeted emissions cuts in both rich nations and the developing world.
Nuclear terrorism poses a grave threat to global security, but seeking silver bullets to counter it does not make sense. Instead of pursuing a perfect defense, U.S. policymakers should create an integrated defensive system that takes advantage of the terrorists' weaknesses and disrupts their plots at every stage, thereby chipping away at their overall chances of success.
