North Korea's No. 2 ranking leader on Monday vowed to strengthen the military and defeat the United States.
The comments by Kim Yong Nam came one week after the North claimed it tested a nuclear device. The alleged explosion prompted the United Nations to pass a series of sanctions against the isolated communist country.
Kim, whose remarks were broadcast on North Korean television, didn't mention the sanctions, approved Saturday by the UN Security Council.
"Our armed forces and people will uphold the army-first policy high and will ceaselessly strengthen the power of politics and the military to firmly safeguard our ideology and system ... and will realize a victory in the historic confrontation war against the United States," he said.
