In response to growing tensions on the Korean peninsula, the U.S. will dispatch a high-tech ballistic missile defense system to Guam.  The Pentagon calls it a precautionary move to strengthen regional defenses.  A Pentagon statement urges North Korea to "cease provocative threats and choose the path of peace" by ending its nuclear weapons pursuits. 

The statement says the U.S. will remain vigilant and stands ready to defend U.S. territory and allies.  The Guam deployment includes missiles and a truck-mounted launcher, along with radar and target acquisition systems.
