Donald Trump reacts to North Korea's failed missile launch

Donald Trump reacted to North Korea's failed missile launch on twitter with the above tweet. North Korea had launched a ballistic missile Saturday but the missile exploded soon after launch without completing it, U.S. officials said. The failed test involved a short-range, non-nuclear missile, which would only be able to hit Seoul, but not Japan. A US official said they had warning of the test and watched it closely.
