this is the "cbs evening news." >> quijano: good evening. i'm elaine quijano, and this is our western edition. as america celebrates independence day, president trump is facing his greatest foreign policy test to date. overnight, north korea launched its first intercontinental missile, one that could potentially strike parts of the united states. late today, secretary of state rex tillerson strongly condemned the launch and called for global action to stop the threat. mr. trump tweeted about the north's leader, kim jong-un, "does this guy have anything better to do with his life?" we have two reports, beginning with david martin. >> reporter: it was the nastiest kind of firework, a north korea intercontinental ballistic missile, capable of reaching at least part of the united states. the missile only traveled 600 miles because it was launched at an extremely high angle, but it flew for 37 minutes, long enough to be an intercontinental missile.

had it been launched on a standard trajectory, it would tve carried over 4,000 miles, far enough to reach alaska. in january, when north korean dictator kim jong-un boasted his country was nearing the ability to launch an i.c.b.m., then- president-elect trump tweeted, "it won't happen." but it has, and it's apparently caught u.s. intelligence by surprise. the u.s. pacific command initially said it was an intermediate-range missile, but that assessment was later revised, and u.s. officials now say all indications are it was an intercontinental ballistic missile. one test does not mean north korea suddenly has a reliable nuclear weapon capable of reaching u.s. soil. david wright, of the union of h ncerned scientists, estimates north korea is still a couple years away from that, but added isere is no denying the significance of this test. >> i would say, a bigger threat than anything north korea has

launched before, in part because ha can reach alaska, but in part because it does show that the koreans are moving forward at a surprisingly rapid pace. >> reporter: the pentagon has prepared options, which involve military shows of force such as long-range nuclear bomber flights over the korean sininsula, and test firings of u.s. missiles based in south korea. one official said the options do not include actual strikes against north korea, although he would not rule out the possibility of covert cyber attacks. after a previously scheduled summit meeting today in moscow, the presidents of russia and china urged a freeze on both north korean testing, and on u.s. military exercises with south korea. the aim of a freeze would be to buy time for all sides to negotiate a way out of an impending collision between donald trump and kim jong-un. ?laine? >> quijano: david martin, thanks. nan tracy in beijing has more on

the role china may play in this. >> reporter: north korean state television's most famous news anchor triumphantly announced what the country called "an historic event." and just moments later, the chinese government urged restraint. a foreign ministry spokesperson said north korea should stop violating security council resolutions, but in an apparent reference to the united states, siid all relevant sides should raing things back to the track of peaceful settlement via dialogue. president trump took a much different approach, tweeting, "perhaps china will put a heavy seve on north korea and end this nonsense once and for all." tina feels it has already done enough to try and rein in its rely. it's stopped buying coal from n rth korea, and has cut its oil and diesel export to kim jong- un's regime. >> i don't think on the chinese side there is any room for significantly tougher sanctions.

>> reporter: tong jao is an expert on nuclear weapons policy in asia. r ere is a perception in the united states that china is not trying hard enough, is not putting enough pressure on north threa. >> china doesn't think that's a fair understanding of the situation. if china steps up its economic sanctions, it's totally possible that north korea will increase the direct threat to china. >> reporter: china has been udwilling to entirely cut off the crude oil supply to north ffrea because that could cause the regime to collapse. elaine, china fears that if kim jong-un has nothing left to lose, that could start a nuclear >> quijano: ben acy,hanks.a. bill richardson is a former u.s. ambassadoro the united nations and is one of the few american politicianwho have negotiated heorth koreans. so mr. ambassador, is this missile launch a game changer for how the west should deal with north korea? >> well, it is a game changer,

because it shows that north herean technologies advance to the point of threatening the united states. alaska. and what it is a game changer to, is kim jong-un is basically saying to president trump: "come at me." he's being provocative. he's trying to put president trump in a box with these provocative acts. >> quijano: so what kind of leverage does president trump and the united states have when it comes to trying to pressure china? >> well, there are two options right now, and they're all bad. there's public statements and diplomacy, and then there's military strike option, which i don't think is realistic, untenable. it will provoke a terrible war. i think, in between, there might t some additional pressures, a new approach that brings international pressure, not just the surrounding countries but perhaps a new coalition of countries that basically wall

north korea off from any kind of economic activity. id quijano: but president trump said that he's prepared to act alone on north korea. what's your reaction to that? >> well, the president should be very careful. the first thing you should do, is not tweet out his foreign policy. i think so far he's been restrained, but at the same time, going it alone, first military strike, that's not going to work. >> quijano: you've negotiated with kim jong-un's father, but the son is quite different. can he be trusted? >> we don't know anything about the son. on's unpredictable. h's dangerous. he's not like the father. with kim jong-un, we don't know what he wants except he wants to be one on the world stage. he wants to be the big guy in the region. he wants to defy the big guys, d e united states and everybody else, and he wants to scare everybody. >> quijano: and the reality of ualogue with kim jong-un? >> i think eventually we have to make a deal, but we need china, and china's not stepping up.

and i think the president is right to jab them a little bit with these initiatives that stir them up, that stir the chinese up. el they really want to help, they can do it. >> quijano: former u.s. ambassador bill richardson. mr. ambassador, thanks for your time. >> thank you, elaine. o quijano: containing north korea is one of many issues likely to come up when president trump meets russia's vladimir putin friday at the g-20 summit in germany. the two leaders are also expected to discuss syria. there is no indication that russian meddling in the 2016 u.s. election will be discussed. ayw jersey's state parks wmopened today, including several beaches, after lawmakers approved a budget four days iste. governor chris christie faced intense criticism after photos showed him sunbathing on a state beach he had ordered closed during the budget standoff. google wants to clear the air. the tech giant that mapped the world's roads to help drivers

i get half-way down that block, the air is going to get worse. >> exactly. you could also take this kind of data and give a biking route, or a walking route, or a route to school, where you would minimize your exposure to pollutants. >> we now have an ability to really make that pollution visible to everybody. >> reporter: steve hammburg is with the environmental defense urnd, which helped pay for the pollution-mapping project. en says detailed pollution maps could even impact real estate prices. ig you don't right now know what you're buying. this will make it transparent. that puts more pressure: let's fix these problems. >> reporter: it's a technology that makes visible what is now mostly invisible, and when it comes to air pollution, what you can't see, can hurt you. john blackstone, cbs news, oakland. >> quijano: today, more than 15,000 people celebrated america's 241st birthday by becoming new citizens. there were more than 65 ceremonies across the country. 76 people took the oath at
