Mapping out new strategy Allies should work closely over North Korea The United States has vowed to map out a "new strategy" for the denuclearization of North Korea in consultation with its allies. White House Press Secretary Jen Psaki said Friday that President Joe Biden believes North Korea's ballistic missiles and other nuclear proliferation-related activities constitute a serious threat to international peace and security. "The U.S. still has a vital interest in deterring North Korea," she said in a press briefing Her remark drew attention as it was the Biden administration's first official statement on North Korea since its Jan. 20 inauguration. The statement is in line with what Tony Blinken, Biden's pick for secretary of state, said during his confirmation hearing Jan. 19 that the U.S. would review its approach toward North Korea.
