Ben tracy is in seoul where millions live in range of north koreas artillery. Ben, good morning. Reporter good morning. The south Koreas Defense Ministry says its closely monitoring what it believes could be another potential north Korean Missile launch. This could coincide with a major holiday that takes place in north korea next week. In the meantime, the south has responded to north koreas six Nuclear Tests quickly and fiercely. South korea brought out its military might, launch ing missiles in a dramatic show of force designed to simulate an attack on north Koreas Nuclear facilities. It happened just hours after north Korean State Television triumphantly announced that kim jonguns regime tested a Hydrogen Bomb, something it called a perfect success. The blast at north koreas main Nuclear Test Site created a manmade earthquake felt in china and russia. Scientists believe it was potentially ten times more powerful than north koreas last nuclear test and at least five times the explosive power the bombs the United States dropped on hiroshima and nagasaki at the end of world war ii. It is a qualitatively different test. Jonathan pollack is an expert on north koreas Weapons Program. It is not only a much more powerful weapon, but it might also be something that is much more miniaturized, in other words so that it would, in theory at least, be able to fit on the warhead of a longrange missile. Reporter just before the nuclear test, north korea released these pictures of kim jonguninspecting what the north claims is a miniaturized hid gynebomb. The regime says it can be placed on an Intercontinental Ballistic Missile capable of reaching the United States. North korea successful tested two bliicbms in july. This is the highest priority for kim jongun. He is wrapped up in this to an extraordinary extent, far beyond what i would have imagined he would have done a year or two ago. Reporter south korea has also announced that it will allow the u. S. To install far more t. H. A. A. D. Rocket launchers in south korea. Major garrett, good morning. Reporter good morning. The sense that both nations are on a collision source is quite simply unmistakesable. North korea keeps moving toward a weapon capable of reaching the United States. In a Statement Released here at the white house yesterday, President Trump said all assets are at his disposal, including the vast u. S. Nuclear arsenal. North koreas successful test of an alleged Hydrogen Bomb far more powerful than the atomic bombs at the dawn of nuclear age brought a certain warning from defense secretary james mat its. Any threat to the United States or its territories including guam, or our allies, will be met with a massive military response, a response both effective and overwhelming. Mattis spoke after an Emergency National security meeting at the white house and outlined every military option. We are not looking to the total annihilation of a country, namely north korea. Reporter before the meeting President Trump attended the church for the national day of prayer for Hurricane Harvey and was asked if it he would attack north korea. Will you attack north korea . Well see. Reporter South Carolina republican Lindsey Graham described the conflict to come if economic pressure or diplomacy fails. Im assuming we drop one file, he fires at south korea and maybe japan. Let me tell you how the war ends. It ends with his utter destruction. Thousands of people could be killed or maimed. Reporter mr. Trump said north korean dictator kim jongun has become a great threat and embarrassment to china. He added, south koreas talk of appeasement will not work. This behavior is completely unacceptable. Reporter the administration is, for the time being, promising to intensify economic pressure. The white house is also considering punishing those who trade with north korea. Anybody that wants to do trade or business with them to would be prevented from doing trade or business with us. Reporter the next level of u. S. Sanctions could focus on large stateowned banks or businesses in china that deal frequently with north korea and the threat of kwcutting off u. S trade with china over the dispute with north korea could affect both nations. Jeff, last year, more than 1 trillion in trade between the u. S. And china. Major garrett, thank you. Cbs National Contributor michael morrell, former acting director of the cia, joins us this morning. Good morning. First of all, do you believe it was a Hydrogen Bomb, and if it is, should we be surprised . Jeff, this was about ten times stronger than the previous test. Hydrogen bombs are typically ten to 100 times stronger than an atomic bomb, so its at the lower end. Our Intelligence Community will be able to determine whether it was a Hydrogen Bomb. Probably too early to say with certainty. Would you be surprised if it is . No, jeff. Not at all. The u. S. Intelligence community has been all over this program for the last 25 years. U. S. Intelligence community discovered it in the early 1990s. Weve been know cussed on it since. Weve predicted accurately how it would evolve and why kim jongun wanted to do this. So there isnt anything that weve seen in the last, id say, five years that has been a surprise. Its all been predictable. We saw south korea with a show of force right after. Now there is word from south korea that north korea may have an icbm launch planned as well. How concerning is this escalation of tension in the region right now . Dana, one of the things to remember is that most wars dont start with intent. Most wars start because people stumble into them. Mistakes are made. Its the way world war i started. So rising tension of the kind weve seen in the Korean Peninsula in the last six months is deeply concerning from that respect. Mike, we heard defense secretary mattis talking about military options. President trump tweeted about economic consequences for countries that trade with north korea and suggested that south korea is appeasing the north. Is that a right approach . Vlad, i think that the best approach here is the right words and the right actions. The right words are sober, right . Its keeping all options open. Its that we will defend our allies at all costs. We will protect ourselves. This is exactly what jim mattis said. Those are the right words. We shouldnt be threatening the north. In terms of action, we should be ramping up the sanctions. We should be building our Missile Defense, and that of south korea and japan, and we should make that known. We should conduct more Missile Defense tests. Thats what we should be doing right now. Michael, if the approach has been sober for years and years and theyve continued this lurch toward the nuclear weapon, what prevents them from getting it . Are you to just assume that its going to happen . Jeff, i think at the end of the day we face two choices. One is a military attack with devastating consequences and no guarantee of success. And the other is acceptance of where they are and where theyre going with containment and deterrence. I think the latter makes the most sense. I think thats where well end up. Michael morell, thank you very much as always, sir. Youre welcome. President trump is expected to announce tomorrow hes ending the socalled daca program. Thats the Obama Program that protects nearly 800,000 immigrants who came to the u. S. Illegally as children. Gop leaders are now pressuring him to keep the policy while they work on a new plan. House Speaker Paul Ryan said it was congresss responsibility to set immigration law. Arizona senator jeff flake spoke out yesterday. There are 800,000 daca kids, kids brought across the border. The median age is 6 years old for the 800,000 when they came across the border. They should not be punished for the sins of their parents. Attorney general Jeff Sessions has called for a hard clean break and wants to use daca as a bargain chip when congress returns.

When you look out and see all of these homes flooded, these businesses. Your office. What do you feel . It hurts. It truly does. These are my friends and neighbors.
