now, this book is very valuable because it sets up as a reminder of how the u.s. found success in iraq and afghanistan and at the same time a nod to what we may have to do differently right now. great to have you on "new day." thanks for being with us. as the situation is evolving or devolving depending how you want to put it there's a new call for boots on the ground. governor pataki said yesterday and echoed by lindsey graham and others do you think it's time for a strategy shift? >> i think it's time for a strategy. i'm not sure most americans or people in the world are sure what our strategy is. but the wider issue is who's fighting against isis. you say we are. you say bashar al assad is fighting against them obviously iranians are helping, the government of iraq shia militia, the united states is helping, some of the persian gulf countries are helping, but it's a group of people.
