Every time. Good evening. We begin with the worldwide reaction today to a dangerous move in syria. Chemicals, dead lly gas loaded onto weapons near an airfield there. One drop could kill within minutes. So, World Leaders are mobilizing tonight, deciding what theyre going to do. And abcs Senior Foreign Affairs correspondent Martha Raddatz takes us inside that story. Reporter today, hillary clinton, overseas, trying to tind some dip mroep matic way to end this increasingly dangerous conflict. 20 months of fighting, 40,000 lives lost. And now the chilling possibility of an air attack with deadly nerve agents. There is no question that we remain very concerned that the regime might very well consider the use of chemical weapons. Reporter a senior u. S. Official saying that over the weekend, the Syrian Military loaded components of the nerve gas sarin into bombs on or near syrian airfields. They have not loaded the bombs onto aircraft, but the threat remains. Once these chemicals are poured into weapons, artillery shells, bombs that can be dropped from airplanes, they can be good up to almost two months. Reporter the Syrian Government claims it will not use chemical weapons. But president assad is feeling the pressure from Opposition Forces who have gained strength and are now moving on the capital, damascus. Jeremy bowen, with our bbc partners, is there tonight and reports assads forces are waging a fierce defense. Throughout the day and after dark, when im speaking to you, there are quite steady explosions of shell fire, outgoing artillery fire, going into the suburbs around the center of the city, where i am. Reporter residents are caught in a worsening cross fire. People who came from areas that are being shelled, they are on the streets, many children, sometimes you see them crying, old people are sleeping on the ground. Reporter but nothing is this horrific war has gotten the attention of u. S. Officials more than this chemical weapons threat. These reports may mean that the United States and our allies are facing the prospect of an imminent use of weapons of mass destruction in syria. This may be the last warning we get. Reporter i can tell you planning for all sorts of con tin jen sips is already well under way. But military action would not be easy. It could take upwards of 75,000 troops to secure those chemical weapons, which no one is eager to provide. But president obama, diane, has warned that using those weapons is a red line. On the story for us tonight, Martha Raddatz, thank you, martha. And now, we want to tell you about another turbulent hot spot, so vital to the United States. There is a battle in the streets outside the president ial palace in egypt, again. And abcs Nick Schifrin is there. Reporter tonight, 10,000 egyptians taking the fight over their future to the president ial palace. They want president mohamed morsi, the man they elected, now to be removed for seizing too much power. Last night, the same street was a war zone. Six killed, 700 injured. The biggest crisis here since egypt, one of americas most important arab allies, overthrew its dictator, hosni mubarak. These very same people filled these same streets two years ago. Today, they are chanting the exact same songs, only replacing mubaraks name with morsis. Tonight, morsi refused to give up the absolute power he seized to write a new constitution. One that many here feel doesnt protect the rights and freedoms they fought so hard for. He has become like using you didnt like mubarak, it is worse than mubarak. Reporter the president s defiance has only increased the tension here. And tonight, these people vow to fight on in the name of democracy. Diane . Nick schifrin in cairo tonight. And now, we return back here at home, to made in america, claiming a kind of victory tonight. The american powerhouse, apple, famous for its giant manufacturing operations in china, has promised to do something they have not done in nearly 20 years. Build some Apple Computers right here in the United States. And abcs david muir, captain of our made in america team, is here with the latest. Reporter diane, as you know, for nearly three decades, apple made its computers in the u. S. Tonight, word one of those lines will bear those three words weve been talking so much about here. Made in america. Tonight, that bold announcement from apple. Ceo tim cook now says some of apples Mac Computers will never year carry those three words, made in america. Cook telling Bloomberg Business week that the Company Plans to spend 1 100 millioner in year t move production from the mac line from china back here to the u. S. It was this year, when asked about the factories they used to have here in america that tim cook talked about the possibility of bringing manufacturing back. There is some manufacturing revival in the u. S. Will there be an apple product ever made again in the United States . I want there to be. Reporter and now a promise that there will be. The vast majority of apple products are made overseas. Wow. Reporter the factories in china made 40 of the worlds electronics. Where just this year, abcs bill weir took you inside for an exclusive look, after working conditions there came under fire. This new move by apple, moving their line of macs back to america, still represents a small percentage of apples overyou a product line. Iphones, ipads still assembled overseas. But cook has made the point before that key components for the iphone are made in america. The processor, the glass in kentucky. Will it ever say on the back of a product, made in the United States . Several parts are from the United States. Reporter apple is now joining a trend that we reported on extensively here on world news. An early wave of american wo companies rethinking where they make their products. Chinese wages have come back. And another reason to come back, location. Make it here and you dont have to ship from china, saving a lot of money. Suddenly, the math isnt adding up. So, they are decides that made in america makes more sense. Yes, its an economic question about being made in america. Its not necessarily a patriotic question. Its an economic question. Reporter one that also creates a Ripple Effect here at home. The other jobs created. Just last night, we introduced you to Arianna Russell in st. Louis, making her own iphone cases and determined to make her design here in america. So, you found a way to do it here. I found a way to do it here. Reporter there was so much interest in those cases last night that her website crashed within five minutes of our report. But its back up and running tonight and she tells us she sold 2,000 of the cases in 24 hours. On this larger announce m from apple tonight, we reached out to our team of economists and they all echoed one another, saying this is about more than just good will. Its now good business. And this move puts an exclamation point on the trend weve all been reporting here. American jobs, back on the case again tonight. Thank you, david. And now, we head out west to washington state, where something brand new in america happened today. And for the first time ever, marijuana is legal in one state. So, what does this mean for other states in the country, and perhaps your family . Heres abcs neal karlinsky.

Reporter in washington state, its now totally legal to smoke marijuana for pleasure, as long as youre at least 21. Im over 21. Sure. Reporter i pull out an ounce of maifrp right now, you are a sworn officer. What will you say to me . Im going to say probably nothing. Reporter in fact, they joke on the official police website, you may responsibly get baked, order some pizzas and enjoy a lord of the rings marathon in the privacy of your own home. But even though its legal to have it, its not yet legal to sell marijuana to the masses. At least not for another year, while the state establishes rules for this now budding industry. Entrepreneurs, or pottrepeneurs, like this former microsoft manager are already making plans to open st starbuckslike stores. Youve got this displayed, you know, encased like a beautiful piece of art. Youre targeting the highend market . That is exactly right. The category of premium marijuana. Think like a fine brandy, a fine cognac. Reporter drug policy experts worry the new law could spark new problems. The price of marijuana will drop dramatically and consumption will increase. That spells bad news for parents and researchers who are realizing that todays maifrn is not your woodstock weed of the 60s. It is much more harmful. Reporter state officials estimate this oncetaboo plant will eventually bring in 500 million in tax revenue per year. Enough to cover the Seattle Police departments entire budget. It becomes legal in colorado next month, and experts say three states, oregon, california and massachusetts, are also watching closely. Just to give you a sense of what the stores might look like, this is a medical maifrn dispenry.
