Trump Is Right: U.S. Should Discuss Ending The Nuclear Umbrella Over Japan And South Korea

The way Washington won agreement from some nuclear-capable powers to abstain from going nuclear is to provide a “nuclear umbrella,” that is, promise to use nukes to defend them if necessary. As a result, the price of nonproliferation in East Asia is America’s willingness to risk Los Angeles to protect Seoul and Tokyo, and maybe Taipei and Canberra too. Trump was right, the U.S. ought to discuss whether those commitments are still in our interest.
