Filling it with a whole bunch of new critters . Good afternoon, everyone. Welcome to the lead. Im jake tapper. Tensions between leaders of the u. S. And north korea are rising sharply as both countries seem to be signaling this time they are not going to blink. The Trump Administration now ratcheting up its tough talk in response to kim jonguns failed Missile Launch over the weekend with President Trump asked by Cnns Jim Acosta today offering a terse warning today to the bellicose dictator. Any message for north korea, sir, kim jongun . Got to behave. Got to behave f. Visiting Vice President mike pence was filling in the blanks, cautioning kim jongun, take a look at the United States military actions in syria and afghanistan, hes saying. You dont want to test President Trump. One thing the white house says it wont do is draw any specific red lines that would trigger a specific response from the u. S. Lets get right to cnns pentagon correspondent barbara starr. North korea could conduct theoretically another nuclear test at any moment, that would be number six. Is it likely if there was another nuclear test the u. S. Would retaliate reporter officials are telling me today theres no immediate plan for retaliation, even if there is a nuclear test, but every step in this crisis does bring it closer to u. S. Shores. Vice president mike pence arrived at the dmz for one reason, to be visible to north korea, making the case to cnns dana bash in an exclusive interview that the Trump Administration is a new sheriff in town. As the president s made clear, that were going to abandon the failed policy of strategic patience, but were going to redouble our efforts to bring diplomatic and economic pressure to bear on north korea. Good morning. Reporter north koreas ambassador to the u. N. Ramping up the rhetoric. It has been created in the situation in which the nuclear war might break out at any minute. Reporter but is the trump doctrine really new . National security adviser general h. R. Mcmaster says all options are on the table, but a peaceful solution is what the president wants just like all other president s. This problem is coming to a head, so its time for us to undertake all actions we can short of a military option to try to resolve this peacefully, and so were going to rely on our allies, like we always do. Reporter the military parade through pyongyang being scrutinized by the u. S. Intelligence community. These canisters could carry a missile capable of reaching the u. S. , but are they real, or are they what one intelligence official called just big green tubes . Spy satellites will be used to figure it out. There are certain infrared signatures, for example, that could reveal the contents of a canister like that. Reporter just hours after the parade, a medium range Ballistic Missile being tested exploded. The second test failure in a row. It may be just mechanical failure, but experts say u. S. Navy submarines. Torpedo course 337. Reporter could secretly attack those Missile Launches jamming their electronics. Depends on some very specialized equipment, and it would have to be done probably covertly if they were actually going to do that. Reporter but out in the open the u. S. Air force announcing a successful long plan test of its improved b61 aerial bomb, both nuclear and nonnuclear components, a bomb that could be vital in striking north korea if it came to that. Much of the focus now, of course, is on pressuring china with economic sanctions against north korea, but no one right now thinks that the north Korean Leader is about to change his ways any time soon. Jake . Barbara starr, thank you. After Vice President pence went to the Demilitarized Zone or dmz and stared into north korean territory this weekend, he spoke exclusively with our own dana bash about the options that the Trump Administration is considering to respond to a threat of a nuclear north korea. Dana, the Vice President is on the Korean Peninsula at a real key moment. Reporter jake, going to the korean dmz for anybody at any time is filled with tension, but even more so now when its the Vice President of the United States amid all of this saber rattling. You said that the era of patience, strategic patience is over. What does that mean in real terms . It was the policy of the United States of america during prior administrations to practice what they called strategic patience. That was to hope to Marshall International support to bring an end to the Nuclear Ambitions and the Ballistic Missile program of north korea. That clearly has failed, and the the add vent of Nuclear Weapons testing, the development of a nuclear program, even this this weekend to see another attempt at a ballistic Missile Launch all confirms the fact that strategic patience has failed. Reporter but what does it mean to end it in practical terms . Its either use military force or find a diplomatic solution that has eluded all of your predecessors . Well, i think as the president has made clear, were going to abandon the failed policy of strategic patience, but were going to redouble our efforts to bring diplomatic and economic pressure to bear on north korea. Our hope is that we can resolve this issue peacefully, and i know the president was heartened by his discussions with president xi. Weve seen china begin to take some actions to bring pressure on north korea, but there needs to be more. Reporter and, you know, this is real for you. You know, that there are estimates that north korea could have a missile ready that could hit the continental u. S. Seattle by 2020 which is going to be on your watch. I mean, is that weighing on you, and is that a deadline that you all have in mind . I know the president of the United States has no higher priority than the safety and security of the american people. The presence of u. S. Forces here in south korea, our longstanding commitment to the asiapacific and ensuring the security of the continental United States will remain the priority of this administration. Look, we want to be clear. Our hope and frankly our prayer is that by marshalling the resources of nations across the asian pacific, not just south korea and japan, other allies and china to bring renewed pressure to bear will achieve our goal of a nuclearfree Korean Peninsula, but the people in north korea should should make no mistake that the United States of america and our allies will see to the security of this region and see to the security of the people of our country. Reporter i know were running late. I just have to ask about your dad. I just heard you say that general brooks gave you some information about his service here. He was awarded the bronze star. What did you learn, and how does it feel to be here in an area that is still at war effectively . I mean, only an armistice, still at war for 67 years. Its very meaningful for me and my family to be here so many years after mire fathers service. Reporter now the fact that the Vice President there at the dmz was stand begun 100 feet from north korean soldiers, its probably not a big surprise that he was more focused on a potential diplomatic solution, but just a few hours later here in seoul, he was standing with the acting south korean president , and he was much more forward leaning on a potential military solution, certainly issued not very veiled threat saying that this president has already conducted strikes in syria and afghanistan, and that the North Koreans should remember that and Pay Attention to, in his words, President Trumps resolve. Jake . Dana bash in seoul, south korea, thank you so much. Is the Trump Administrations position on north korea really all that different from previous administrations .

High tensions on the Korean Peninsula after more threats from north Koreas Nuclear program. And joining me now is republican congressman darrell issa of california. He serves on the house northern Affairs Committee. Congressman issa, thanks so much for joining us. Appreciate it. Thank you and thanks for covering these important issues. Vice president pence visiting south korea said the era of strategic patience with north korea is over. What does that mean, do you think, and what does that mean in terms of what the u. S. Does now . Well, i think half nearly 67 veers, the Vice President was saying that we are going to hold china accountable for the actions of north korea. For all those years since just after the landing, china has been the protectorate of north korea and this enabler of this awful behavior. How is this administrations posture towards north korea different from previous administrations, do you think . Well, i think in the past there was an attempt to reason with north korea, make deals with north korea, but thats failed time and time again, and now the only power broker in the world, and particularly in the region that can affect north koreas action would seem to be china. The chairman of your committee, the house northern Affairs Committee ed roy over the weekend said that hes pushing a bill that would allow sanctions on ten chinese banks that could business with north korea. Do you support that bill . Mike greenwell, i havent seen it, but the concept that we hold china responsible for enabling north koreas activity, whether its through banking, which obviously allows them to buy these materials, or even the purchase of coal that gives them hard currency, i think it is an important Pressure Point in a new pivot towards chinese responsibility. Vice president pence said we saw the resolve of President Trump with the strikes in syria and afghanistan and warned, quote, north korea would do we will not to test the resolve or strength of the armed forces of the United States in this region under President Trump. What do you think, if anything, should trigger use of military force by the u. S. . Well, i think that you have to not have a specific action but rather a recognition that a measured response to provocative activities by north korea can be expected. Again, you know, they tried to launch a missile just the other day. Depending on where that went. That certainly would be considered to be a provocative act, but i think the important thing is that those two attacks done during this administration are recognition that the National Security council is working, that a team of people very diverse, security people made unanimous decisions for those measured responses in the other two areas. Was Vice President pence, do you think, trying to send a message to north korea by going into the dmz and going basically up to the border and staring down north korean troops . I think he was sending a message to china, and i think when the president met with the premier that was also something that undoubtedly was brought up, that you have a powerful nation that is enabling a rogue small rogue nation that it has protected for over 60 years to do things that are internationally just wrong, but, you know, theres another point which is that i think theres a recognition of human rights. North koreans are five or six inches shorter than south koreans. Thats a difference in nutrition. For all these decades weve seen North Koreans suffer under a failed government, and theres got to be a recognition that chinas moving forward but north korea isnt. North korea displayed new missiles or at least they looked like missiles during a military parade in pyongyang over the weekend during their holiday. A scholar at the Woodrow Wilson center described what were going through right now as the cuban missile cries in slow motion. Do you agree . I do, and the similarity is that the cuban missile crisis was a decision by russia to use a surrogate to threaten the United States, and china has effectively been using a surrogate to threaten japan and other nations in the region, and ultimately could threaten the United States. Republican congressman darrell issa, thank you so much. Appreciate it, sir. Sure thing. The urgent manhunt for the alleged facebook killer is expanding. Police are now offering a 50,000 reward as people in five states are being told to be on the lookout. Stay with us. Hey, bud. You need some help . No, im good. Come on, moe.

President trump was at maralago for the easter weekend, his seventh weekend at the club in the 13weekends of his presidency. He visited his golf course at least twice, a total of 19 visits to a golf course since becoming president. His numerous tweets attacking his predecessor for golfing during world crises notwithstanding such as this golden oldie from 2014. Can you believe that with all of the problems and difficulties facing the u. S. , president obama spent the day playing golf. In addition to his trips to the 18 holes, the president fired off ten tweets since just yesterday, ranging from easter well wishes to dismissing protesters as being paid to weighing in in his own imimable style on special elections this month. Cnns jeff zeleny is with us and this morning the president participated in the 1 is 39th annual easter egg roll. It wasnt all fun and games hemp also said that north korea has got to behave. Yak, he did. He said north koreas got to behave. He didnt elaborate exactly what that means or iffy in do not behave, but theres no question that north korea and the emerging threat is emerging as one of the biggest Foreign Policy challenges of this new administration as it reaches its near 100day mark at the end of this month. Now, the white house is not taking any options off the table on north korea. They are also not saying exactly what a red line would be in north korea. Weve heard so much though about strategic patience of this administration. The Vice President , of course, said that in south korea. Well, today, White House PressSecretary Sean Spicer explained exactly what that means, strategic patience. The era of strategic patience was a policy that the Obama Administration enacted, to basically wait and see. I think we have now understood that that policy is not one that is prudent for the United States, and i think thats why youve seen steppedup efforts, particularly with respect to china. Reporter so the president is now counting on chinas help with north korea, and hes indeed being patient and waiting for that help that he hopes to materialize. But, jake, its a stunning turnaround, the language, the tone, the entire posture towards china that this president had during the campaign when he accused china of raining the u. S. , taking jobs from americas heartland. Well, the president will travel to wisconsin tomorrow to talk about some of those jobs, even as he hopes and waits for chinas help in north korea.
