U.S. wants more U.N. sanctions over North Korea’s nuclear arms, warns time is short

Secretary of State Rex Tillerson called Friday for new economic sanctions on North Korea and other “painful” measures over its nuclear weapons program, as the Trump administration warned that it would take military action if diplomacy failed.

“Failing to act now on the most pressing security issue in the world may bring catastrophic consequences,” Tillerson said during an unusual high-level session of the U.N. Security Council called to review what the Trump administration calls its most dire national security concern. “The more we bide our time, the sooner we will run out of it.”
