The United States said to North Korea, "You'd better not launch that rocket!" (at least in words of the same spirit).
Japan said to North Korea, "We will shoot down any rockets that fly over Japanese territory."
Well, North Korea launched the rocket, and it flew over Japanese territory.
The United States's response? "You are very bad, North Korea. Shame on you."
Did Japan shoot down the rocket? No.
So what did North Korea learn from all of this?
It learned that the U.S. and Japan are full of hot air.
Man, for the days of George W. Bush! Had he been president, we would have shot down that rocket and invaded Uruguay.
