PYONGYANG, North Korea (AP) -- President Donald Trump's tweets are adding fuel to a "vicious cycle" of tensions on the Korean Peninsula, North Korea's vice foreign minister told The Associated Press in an exclusive interview Friday. The official added that if the U.S. shows any sign of "reckless" military aggression, Pyongyang is ready to launch a pre-emptive strike of its own.
Vice Minister Han Song Ryol said Pyongyang has determined the Trump administration is "more vicious and more aggressive" than that of Barack Obama. He added that North Korea will keep building up its nuclear arsenal in "quality and quantity" and said Pyongyang is ready to go to war if that's what Trump wants.
Tensions between Pyongyang and Washington go back to President Harry Truman and the 1950-53 Korean War, which ended in an armistice, not a peace treaty. But the heat has been rising rapidly since Trump took office in January.
