Pyongyang knows there is no way to use their weapons for gain that would not immediately provoke massive counter-costs.
Since the launch of a North Korean medium- to long-range intercontinental missile this month, there has been much anxiety about Pyongyang’s ability to strike U.S. cities. It seems likely that North Korea can at least strike Alaska’s largest city, Anchorage. Some analysts have suggested Pyongyang already has the capability to strike the east coast of the United States. Skepticism may be warranted. North Korea may have trouble with missile reentry, guidance, warhead miniaturization and other technical issues. But nonetheless, it appears quite likely that if Pyongyang does not yet have the ability to strike the lower forty-eight American states, it will soon. Last month, I suggested the United States is on countdown of sorts. North Korea is rushing toward a nuclear ICBM, and Americans will soon be forced to adapt to it, or fight. It seems that decision fork is coming sooner than many expected.
