What Would Japan Do if They Discovered North Korea Was About to Start a Nuclear War?
While a preemptive-strike capability for Japan isn’t impossible, it is more difficult than many observers realize. Building the force necessary for prosecuting an air campaign would certainly necessitate busting the 1 percent GDP cap on defense spending that Japan currently has in place, but like the prohibition on “offensive” weapons, that too is a policy matter that can be reversed. Another, less lethal national security concern is Japan’s debt problem, which is currently north of 200 percent GDP. Whatever path Japan decides to take won’t be easy.
