>> they need the assistance right now. how about then on the no-fly zone? are you in agreement that putting in place a no-fly zone would immediately trigger a world war iii? >> fredricka, this is a really tough problem for nato and the united states. i have experience with no-fly zones, particularly in libya. i was an operations officer and according to the u.n. security council mandate to stop the general side of gadhafi, we were told to establish a no-fly zone. you may recall that secretary of defense bob gates at the time said a no-fly zone is yet another attack on another arab country. he did not want to do it. we ultimately did do it, and the problem with no-fly zones is you just can't fly aircraft into air space over ukraine and say, okay, we've established a no-fly zone. you have to mitigate the risk against those nato or u.s. aircraft, and that means eliminating the threats to those aircraft. that means kinetic strikes
