the iraqi syrian border region where a lot of militants have moved in months. there has been a race to recapture that part of the country, syrian regime backed by russian air power, and the other hand, you have the u.s. led coalition and that is expected to be a tough fight on both sides of the border, also in anbar province, in iraq, and those areas that are still under isis control. but, again, it would seem -- you're seeing city after city are collapsing, being recaptured by forces both in iraq and syria, so as u.s. officials would say, the days of isis as a group that controls territory are numbered. but that doesn't mean the end of isis this terror group, that is so lethal, that still possesses the capability to carry out attacks, not just in iraq and syria, but around the world. >> absolutely. all right, thank you.
