North Korea said on Tuesday it has moved strategic rocket and artillery units into top combat position in preparation for a strike against the United States.
The Pentagon announced on Friday that it will spend $1 billion to add 14 interceptors to a West-Coast-based missile-defense system, responding to what It called "faster-than-anticipated North Korean progress on nuclear weapons and missiles."
Since North Korea conducted underground nuclear tests on February 12, the international community has taken renewed interest - and consternation- by their bellicose actions. These tests prompted the United Nations Security Council to order harsher sanctions against the already isolated country. In return, North Korea has threatened the U.S., and its allies "all out war."
