Right on if you dig your bones, protect them. All cbs cares more than 200 additional u. S. Troops will be joining the fight against isis in iraq today defense secretary ash carter made that announcement in baghdad. Nearly all u. S. Forces were pulled out in 2011. But the u. S. Presence has been rebuilding. It doubled to 3,100 in 2014, 500 more in june, now, the total will be more than 4,000. One u. S. Marine was killed last month. Today, president obama said this. About the possibility that mosul, iraqs second largest city could be liberated from isis. As we see the iraqis willing to fight and gaining ground, lets make sure we are providing them more support. We are not doing the fighting ourselves. When we provide training and we provide special force whose are backing them up, when we are gaining intelligence, working with the coalitions that we have, what we have seen is that we can continually tighten the noose. My expectation is by the end of the year, we will have created the conditions whereby mosul will eventually fall. The president spoke today with charlie rose, cohost of cbs this morning. Charlie also asked him about an enduring mystery from 9 11. 28 pages of government documents that deal with saudi arabia which remained classified. Youll remember that 15 of the 19 hijackers were saudi citizens. Have you read it . You know i have a sense of what is in there. But this has been a process which we generally deal with through the intelligence community. And jim clapper our director of National Intelligence has been going through to make sure that whatever it is that is released is not going to compromise some Major National security interest of the United States. And my understanding is that he is about to complete that process. But the point is, it has been a long time. A long time . That i will acknowledge. And hopefully that this process will come to a head fairly soon. What about this legislation in the congress that will allow families to sue the saudi government . And other government in different circumstances . Exactly. I am opposed because of the second clause in your sentence. This is not just a bilateral, u. S. saudi issue. This is a matter of how generally the United States approaches our interactions with other countries. If we open up the possibility fee that that individuals in the United States can routinely start suing other governments, then we are also opening up the United States to being continually sued by individuals in other countries. You can see charlies interview including the president s relationship with vladamir putin tomorrow morning on cbs this morning. Then later, on the charlie rose show tomorrow evening on pbs.
