POPPY HARLOW, CNN ANCHOR: We are following breaking news this morning. Secretary of State Rex Tillerson saying the U.S. is prepared to take military action against North Korea, saying that during his visit to the region. Our Alexandra Field is live in Seoul with the breaking details. Very clear in his word choice there.</s>ALEXANDRA FIELD, CNN INTERNATIONAL CORRESPONDENT: Yes, this is really a major development, Poppy. It came just as Secretary of State Rex Tillerson returned from the DMZ, the heavily fortified border between South Korea and North Korea, arriving in Seoul, where he spoke to reporters, declaring that the policy of strategic patience had come to an end. He has said that 20 years of diplomacy has failed when it comes to dealing with North Korea. And he has been saying it is time for a new and different approach. I had the opportunity to ask the secretary of state what a different approach could really entail, because for people that have watched North Korea for years, they know that it appears so many of the U.S. allies have tried it all when it comes to North Korea. That's when he said that a military option would be on the table, would remain on the table. He made it very clear nobody wants to see any kind of military conflict with North Korea, but that if North Korea threatened South Korean forces or the U.S. forces who are stationed right here on the peninsula, that the military option would be on the table. He also made it clear a military option would remain on the table if the North Koreans escalated their nuclear program to a point where the U.S. felt it was time and necessary to act -- Chris.</s>CHRIS CUOMO, CNN ANCHOR: All right. Alexandra, this has been a point that the U.S. has been slow to go, what will be the implications. Appreciate the report. Another fiery White House briefing. Sean Spicer against everyone. The press secretary angry, defiant, defending the president's wiretap claims still. The question is: does he have any proof to back up his passion?
