nick pateing walsh, as i always say, be careful over there. talking more about the iraqi military offense on mosul. joining us from chicago, illinois, republican congressman add ang kinsberg, remains a major in the u.s. air national guard, former member of the house arms services committee. congressman, what are you hearing about the progress in this battle to liberate mosul? well, seems like the front end of this battle has gone pretty well. scene in mind, what you have right now is outskirts. it s not the main part of the city. the second biggest city in iraq, which you can compare to, you know, milwaukee or something like that in terms of size. the real question s going to be, does isis decide to stay and fight to the end? in which case, you have a block to block fight. looking for boobytraps, ieds and it will be very slow going, or does it at some point isis make a stand and decide to melt away and go to, you know, spiritual center of raqqah? that s the real question.
