Still to come on the newshour a delicate balance of alliances under threat after air strikes hit isis and kurdish targets president obama promotes his economic and human rights agenda for africa and much more. Ifill turkey and the u. S. Are working on plans to sweep Islamic State fighters from a strip of land across the Turkish Border with syria. This comes as istanbul steps up its air campaign against the Extremist Group and its crackdown on kurdish insurgents. Special corespondent Jane Ferguson reports from southern turkey, where many are holding their breaths. Reporter american fighter jets will soon be launched closer to the Islamic State group than ever before. From this turkish base at incirlik, they will pound the Extremist Group just across the border in syria. A new deal between the u. S. And turkey will allow americans to launch air strikes from turkish soil and increase turkeys role in the fight. Turkey will reveal the details this is a major turnaround for turkey, which has been criticized for not doing enough to tackle isis. Now, deadly attacks by the group along the border have pushed the turkish government to act. At this outpost, 100 yards from isis, a turkish soldier was shot dead by the group last week. El beyli village is the nearest turkish village. People here are terrified that isis is simply too close. Some told us they want more soldiers to keep them safe. translated we are so nervous. We want to see a normal life again here. We cannot sleep. Reporter an hour down the road, the groups power is alarmingly apparent. In areas like this along the Turkish Border, isis are so close to turkey that you can see their flags flying. Just behind me on that wall there is an isis flag, just feet away. Now what the turkish government want to do is to push isis back from these areas to create some sort of safe zone or buffer. Its clear turkey believes once you establish a safe zone, people will go back to it. Reporter stephen cook is a middle east scholar of foreign relations. It will become a place that moderate Syrian Forces will expand march against the Islamic State as well as the assad regime. But one can imagine a whole host of scenarios that pull turkish and potentially American Forces further into the syria fight. Reporter the Islamic State has also hit the Kurdish People in eastern turkey. Ethnic kurdish communities straddle the border between turkey and syria. Kurdish rebel fighters inside syria have been battling isis for months. Last week a suicide bomber killed 32 young activists in the kurdish town of suruc inside turkey. The attack shocked the nation and increased calls for action against isis. The young People Killed here were planning to bring toys for children across the border a few miles to kobane, where Kurdish Forces had routed isis earlier this year. The fivemonthlong battle for kobane was a significant victory for the Kurdish Forces. It showed their growing strength inside syria. The turkish government watched with concern those kurdish gains in territory with concern, fearful their own kurdish population may push harder for independence. Now this new deal with the American Military opens the door for turkey to fight not only isis, but the kurds. And its already happening. Turkish jets bombed both isis and Kurdish Forces in iraq as soon as the deal was announced. A twoyearold ceasefire with the kurdish rebels in turkey is now believed to be over. People back in suruc say turkey is only starting another war inside its own territory. translated in the name of operations against isis, we dont want to attack turkey. We see egypt, libya and iraq and the wars that are going on there and we dont want this to happen in our area. Reporter although american jets have been helping the kurds win territory from isis in syria, u. S. Officials now say they support turkeys strikes against kurdish targets. Turkeys involvement in the war against isis could prove a crucial turning point in u. S. Led Coalition Efforts to destroy the group. Opening a new fighting front against kurds in the region simultaneously, will change the delicate balance of alliances in an already complex war. Ifill i spoke to Jane Ferguson a short time ago. Jane, were talking now about an i. S. I. L, i. S. I. S. Free zone along the border now. Why is it turkey is interested in this now . Well, turkey is under increasing pressure. The turkish president is under pressure from its own population to do something about i. S. I. S. And not be seen a being soft on terror. Violence has shocked turkey in the last week. Whats complicated issues for the turkish government is there are so many kurdish rebels on the syrian side of the border. Those rebels have been making Massive Gains against i. S. I. S. And taking terrorist away from i. S. I. S. Whenever they have victories, as they have had in the recent months. That complicates things for turkey because the turkish government are dealing with a large kurdish minority in their country who, for decades, have been pushing for independence and they, of course, still want to see any bolstering of kurdish calls for independence right on their border and in their territory. Ifill you mentioned the word complication more than once. There are a lot of complications. Another one is syria themselves agreed to anything which involved in this collaboration could help the proassad forces in syria. Syria. This, of course does complicate things because it will be fighting i. S. I. S. And not necessarily assad and that is something that the turkish government have been criticizing the coalition for. They really wanted airstrikes against assad. They wanted a nofly zone imposed. So for them they had been holding out for that. But at the minute, the details of this deal will be revealed tomorrow, probably most likely at that n. A. T. O. Meeting. So we wont know the details just yet. But the plan, as far as officials are telling journalists, would be to create this buffer zone to allow certain rebel groups not kurdish rebel groups, around certain rebel groups described as moderate to take over that specific area, that would give them room to resupply, to maneuver, to basically operate in the area around aleppo north in aleppo city. Ifill we dont know how far the buffer zone would extend. Its not clear four in it would go. Its unlikely it would go all the way to aleppo city. That would be an enormous military target. But if it could just move in far enough to be able to number i. S. I. S. Away from the border so that they no longer can touch the Turkish Border, that would be significant in itself militarily because that would affect their link to tot side world, essentially. Ifill Jane Ferguson, reporting for us tonight in turkey, thank you. Woodruff president obama continued his visit to africa today, making a personal push for peace and calls for democracy. Reporter the starspangled banner greeted the First American president to visit africas second mostpopulous country. But after the pomp, the president spoke of urgent business, not in ethiopia, but in its neighbor to the west south sudan. Since the u. S. Helped midwife the founding of the worlds newest nation in 2011, civil war has left tens of thousands dead and displaced two million more. Our hope is that we can actually bring about the kind of peace that the people of south sudan so desperately need. Reporter the president and African Leaders discussed options, including sanctions, if a peace deal is not reached by august 17th. Mr. Obama urged inclusion, and respect for human rights, in a News Conference with ethiopias prime minister. I believe that when all voices are being heard, people know that they are included in the political process, that makes a country stronger and more successful and more innovative. Woodruff that message was also central to the president s visit to kenya over the weekend. It was a highly anticipated visit to his fathers homeland and mr. Obamas first in nearly three decades. Kenyans lined the streets to welcome the president , whom they see as one of their own. But security precautions prevented him from greeting many of the residents so thrilled to see the kenyanamerican president , as he referred to himself or visit his fathers village. He did, however, attend a private dinner with members of his family including his grandmother and halfsister. And he cut a rug at a state dinner held in his honor joining in on a traditional dance. Aside from the celebrations, the president also pushed his human rights message. Kenyas president , uhuru kenyatta, emphasized the threats of terrorism facing his country and promised to work toward equal rights for all. We agreed together that we can build a future in which our people of all faith, cultures live peacefully together with reporter but the country has a checkered record when it comes to human rights. In 2010, kenyatta himself was named a suspect in crimes against humanity by the International Criminal court. President obama spoke about corruption, ethnic divisions, and human rights urging kenyans to choose the path to progress. And he had stern words for the treatment of people based on Sexual Orientation even as kenyatta dismissed gay rights as a nonissue for kenyans. So, im unequivocal on this. The idea that they are going to be treated differently or abused because of who they love is wrong. Full stop. Reporter tomorrow, in addis ababa, mr. Obama will be the First American president to address the african union. Joining me now to discuss the visit and president obamas record on africa is career diplomat and former assistant secretary of state for the bureau of African Affairs under president obama, Johnnie Carson. Hes now a Senior Advisor at the u. S. Institute of peace. And william gumede, an author and professor at the university of the witwatersrand in south africa. We welcome you both. Professor, how do you think this trip has gone and how much difference do you think its going to make . Unfortunately, this trip is almost coming at the tail end of the obama presidency. You might understand this has been happening in the last couple of years in africa. China has become a big factor in africas growth. Obama coming to africa has made democratic noises but almost a little too late. Woodruff ambassador carson, what about that . Is the president coming too late . Absolutely not. This, i think, is turning out to be a very substantive and positive trip with president obama focusing on expanding trade and commercial opportunities with africa with these two countries and the United States and strengthening the Security Partnership that the United States has had with both kenya and eat nopia. The president is also getting a chance to talk about some of the new initiatives that he has been responsible for power africa to substantially increase the amount of electrical power reaching african cities and communities, feed the future which is designed to promote a green revolution across africa, to help end starvation and famine at the village level and to expand agroindustries at the upper level, and particularly a focus on the youth, the next generation. So this is an important trip, and its the fourth trip to the continent and may not be his last. Woodruff well professor gumede, these are specifics, this has to do with working with the economy and young people. Well, what has been happening in the next couple of years, you know, weve seen the longest growth spurt in africa, you know, i mean, since independence and since the second world war. If you look at how the dynamics of this growth, the dynamics of this growth has been driven really, you know, by newlyemerging markets buying africas products, getting engaged in africa whether china or india. That is the nature of it has been a big gamechanging couple of moments the last couple of years in africa, and in the u. S. , you know has almost lagged behind and really going to have to work much harder, you know, to catch up with what has happened on the continent. If you just think about it, at the moment, Civil Society on the continent where the new African Leaders should be coming from, you know, have struggled the last couple of years because, you know the foreign funding used to get in the path has declined up the Global Financial crisis and many of the several societies democrats in africa have struggled and hoped that the u. S. Would have played a much bigger and stronger role in providing them with capacity. Woodruff let me put that question to ambassador carson. To listen with to what the professor is saying, sounds like the u. S. Is dropping the ball, china has been active there, there has been an opportunity to engage and the u. S. Hasnt taken advantage of it. The United States has been deeply engaged in africa, not only as a Development Assistance partner, but increasingly as a trading partner as well. The United States remains one of the largest, single, bilateral contributors to Development Assistance in africa and the United States remains one of africas largest trading partners. I think that president obama, over the last several years, has gone out of hi way to encourage american bymen and investors to increasingly look at africa as the last Global Economic frontier. You may recall, judy that in 2014, president obama held the first u. S. Africa summit and the first day of that summit was devoted all to economic, commercial and investment interest. Woodruff professor gumede it almost sounds like youre talking with two diff
