SEOUL, South Korea (AP) — The United States signaled a tougher strategy toward North Korea on Friday that leaves open the possibility of pre-emptive military action and rejects talks with the communist nation until it gives up its weapons of mass destruction.
"Let me be very clear: the policy of strategic patience has ended," said Secretary of State Rex Tillerson. "We are exploring a new range of diplomatic, security and economic measures. All options are on the table."
