International security/Cheaper but doubtful way to provide security in Asia

The prospects for the U.S. being able to project its power and defend its allies in Asia are not good. The U.S. security guarantee – known as “extended deterrence” – was never really tested in Asia the way it was on a daily basis in Europe during the Cold War. Understandable, since Asia was not the global center of strategic gravity. But it is now. Military modernization and expansion by all the players is causing greater friction between the tectonic plates of Japan, China, South Korea, and the United States, testing the limits of U.S. extended deterrence, which currently minimizes the role of nuclear weapons. However, the very foundations of this concept were designed to deal with a land, European theater, not the Asian maritime environment.
...But there is a better, cheaper way to provide security in Asia. Washington should encourage its allies to acquire their own nuclear weapons, and let its Asian allies defend themselves with the weapon that is the great equalizer.

Should U.S. Allies in Asia Get Their Own Nukes?
