I know that Richard Bolton wants us to hit North Korea if it launches, and I really hope that nobody in the current administration is listening.
You see, it's not like the Japanese haven't either (a) known this was coming for over a decade; or (b) lacked the military or industrial ability to see to their own defenses--the Japanese military has roughly 230,000 troops, 330 combat aircraft, 800 tanks, and 119 major warships.
It's just that the Japanese (with our unwavering support) apparently lack the political will to defend their own country:
After North Korea test fired a Taepodong-1 ballistic missile over Japanese airspace in August 1998, subsequent North Korean tests as well as other issues contributing to rising tensions between the two countries have led to increased interest in Japan for a ballistic missile defense (BMD) system. Japan is in the process of deploying a multi-tiered BMD system comprised of upgraded Aegis vessels and Patriot PAC-3 missiles. Legislation that would allow authorities to authorize shooting down an incoming ballistic missile is also being considered. In December 2004, Japan and the United States signed a memorandum of understanding creating a general cooperation framework for joint development of a sea-based BMD system.
Legislation allowing the air force to shoot down an incoming missile is being considered?
It would be the essence of a Libertarian foreign policy that a Japan not only capable but willing to defend its own airspace would enhance regional security around the Pacific Rim without a massive, intrusive, and expensive American military presence.
Waiting. Holding my breath. Turning blue.
