So North Korea is getting into the 4th of July Spirit by firing off some bottle rockets. Most of what they launched were short-ranged missiles which landed in the Sea of Japan. Their one attempt at firing an intercontinental-ranged missile failed badly. Turns out rocket science really is hard.
But it works out nicely. The United States has built a ballistic missile defense system that doesn't work in order to stop a North Korean missile that doesn't work. Nice.
