Remember North Korea?

"North Korea has mounted a rocket on a launchpad on its northeast coast, American officials said, putting Pyongyang well on track for a launch the U.S. and South Korea warned Thursday would be a major provocation with serious consequences.

Pyongyang says the rocket will carry a satellite, but regional powers suspect the North will use the launch to test the delivery technology for a long-range missile capable of striking Alaska. They have said the launch - banned by the U.N. Security Council in 2006 - would trigger sanctions."

A serious threat from North Korea is being met with an empty threat from the USA.

If we're not going to do anything of substance, empty threats only make us look weaker.
