We begin with the Trump Administration searching for the right response to north koreas firstever Intercontinental Ballistic Missile test. The most powerful missile the north has ever tested marks a dramatic change in the threat to the u. S. From kim jonguns regime. U. S. Forces in south korea responded overnight with a show of deep strike missiles. Those missiles were fired into south korean waters. Secretary of state Rex Tillerson is promising stronger measures against kims government. But the u. S. Has very few workable options most feel. The north Korean Leader said american jerks would not be very happy with this gift sent on the july 4th anniversary. Ben tracy is in beijing with a growing International Reaction to the missile test. Ben, good morning. Reporter good morning. Well, china and russia are now saying that they oppose any effort to resolve the north korean crisis by force or with sanctions that would strangle the country economically. The u. S. And south korea seem to be making a different argument this morning with missiles. In a largescale military exercise wednesday, the u. S. And south korea launched a barrage of missiles into the east sea. The message to north korea, we have weapons too, and they are not far away. In a statement, the pentagon said the u. S. Will use the full range of capabilities at our disposal against the growing threat from north korea. After the u. S. Military confirmed that the regime successfully launched an Intercontinental Ballistic Missile on tuesday, south korean Officials Say the missile, known as the hwasong14, is a twostage weapon with an estimated range of nearly 5,000 miles, capable of hitting alaska and even the west coast of the United States, according to some experts. Each missile that north korea tested before this was back in may. That had a range of maybe about 300 miles. So this is considerably longer. I think the kinds of things theyre doing will allow them to continue to increase the range. Reporter north korea believes that possessing Nuclear Weapons capable of hitting the u. S. Is the only way to be taken seriously. The regime is developing its weapons more rapidly than most experts thought possible. It claims that tuesdays test improved the accuracy of its icbm and that it can carry a largesize heavy Nuclear Warhead. But one test does not mean that north korea now has a reliable Intercontinental Ballistic Missile system, and we dont know if theyre able to put a Nuclear Warhead on it as they claim.

Reporter Nuclear Policy pert Jeffrey Lewis believes increased sanctions or threats will only push north korea to develop more weapons. North koreans realize that these weapons are basically the only thing they have going for them. Its a fantasy to imagine that pressure alone is going to solve our problem. Reporter President Trump has pressured china to pressure north korea to stop developing Nuclear Weapons and he is reportedly deeply unhappy that china is drag its the feet. Gayle. Cbs News National security analyst Fran Townsend was a former advisor to president george w. Bush. She joins us at the table to discuss. Hello, fran. Hello. July 4th seems like a big ole in your face move. Has that changed the game, do you think . It absolutely has changed the game. This was a successful Intercontinental Ballistic Missile launch. That means it has further range than anything up to now. We knew they had medium and shortrange missiles which were much more of a regional threat. This now represents a direct threat to the United States. And so were going to have to do things differently. Sanctions alone have not worked. And i think the timing of it allows the president now to put this at the top of his agenda in his g20 meeting. But i should say its a big step yet to say once youve got the missile to be able to successfully marry the Nuclear Warhead and have a successful launch. The question, fran, you say sanctions dont work and we have to do something. What is that . We have to get our the other countries to care about this as much as we do. You know, i think it isnt right to say that its not you know, north korea doesnt represent a regional threat. During the Bush Administration we pushed quite hard to get our regional partners to pay more attention to this. China is going to have to really seriously implement. The reason were hearing President Trump is unhappy is we know that 80 of the sort of supply chain into the program in north korea comes through china still. But what incentive does china have to do something beyond what theyre doing right now. You just heard the experts say they dont care, its not their problem. We should be honest about why china is not incentivized. China has always cared about the u. S. Presence on the peninsula and so their great fear is an increased u. S. Presence if the north korean government falls. We have to put that on the table while still reassuring our south korean allies. So its a delicate dance. But what weve been doing all along hasnt worked and so were going to have to be willing to put new things on the table. Past president s have tried diplomacy, it hasnt worked. There are 28,000 u. S. Troops on that border. We know in the past ten years its heavily armed, that demilitarized zone. So where do you go then . Is diplomacy really an option here . Dpliplomacy alone and diplomy with sanctions alone has not worked, right . We have to be honest with ourselves. I think it underscores the importance of the Missile Defense system that were putting in for south korea. I also think the thing we havent talked about yet is the importance of our missile intercept capability. And so it may be the North Koreans ought to be prepared the next time they do just a missile launch, the United States might try to use its capability to intercept that. But no one is fully confident those intercepts will work. They did try the icbm and they said it worked but that was designed to succeed. Thats right. And so i think what youre going to see in congress and here in the United States is a real call to put further investment in that technology. Fran townsend, thank you very much.
