I believe the B52's are being used in a standoff role and throwing cruise missiles over the fence as there is still a reasonable anti-aircraft threat. This will change as the boys give the place a tickle up and shut down the Iraq military. Once again as per my previous post showing live footage is one thing, but these aircraft are flying through civil airspace, talking on civil frequencies and essentially anyone who wants to know...can. This would change if there was higher perceived threat ie. North Korea, and the ops would be far more subversive.
