smerconish, always good to see you both. thank you so much. tuesday is the anniversary of 9/11. in today's office politics my conversation with msnbc terrorism analyst evan coleman. i began by asking him about his greatest fear for an attack here on u.s. soil. >> my greatest fear, honestly, is that an al qaeda affiliate group. a group that we haven't been looking at that closely. aqap is a good example of that. before the underwear bomb plot, no one had heard of al qaeda in yemen. my concern is that you have an al qaeda affiliate group that's not being heavily focused in on. they identify u.s. nationals who they can work with who are under the radar who are home grown, who are esoteric or at the fringes of the jihadi community. those individuals are able to come up with a plot that is simple, is easy to carry out and causes major economic damage. that is exactly what al qaeda is
