very bad development. >> final thought in terms of the length of this. there's going to be a forest fire that just burns and sfwhurns i think if we continue to allow in many cases our allies, countries like saudi arabia which have a sectarian agenda, and our obsession with iran, to dictate or affect policy to the exit tent to which they have, our letting the israelis call the shots sometimes, these things are going to be harmful. the united states has to understand that it has absolutely no dog in a sectarian fight. it helped to create this but it's a problem beyond us. and we cannot control or determine outcomes in this region. i agree with peter, they're potentially very dangerous, not just for the region, for the world. >> final, final thought. bob gates. the man has a reputation for complete discretion and then he writes this memoir that does not seem the sole of discretion. what was your big takeaway. you worked with limb. >> good friend.
