By Ed Flanagan, Producer, NBC NewsNorth Korea vowed to boost its nuclear capabilities on Wednesday after the United Nations Security Council unanimously passed a resolution condemning its controversial rocket launch last December (http://www.msnbc.msn.com/id/50167891/ns/technology_and_science-space/t/north-korea-says-it-successfully-launched-satellite-orbit/).
“The present situation clearly proves that (North Korea) should counter the U.S. hostile policy with strength, not with words,” the country’s foreign ministry warned in a statement.
North Korea pledged in the statement to bolster its military capabilities and to build up what it called a “nuclear deterrence."
