Jacko has always been upfront in his anti-US views and very pro-RAF (The two viewpoints do NOT have to be synonomous by the way). It is just anathema to him that a mistake (was it? Or did the CAS pilot(s) go in as close as they dared since everyone in theater is no doubt hyper-sensitive to another 'blue on blue'? Until that bit is known, perhaps the mud-slinging should be withheld?) could be a non-US one.
I don't know his professional work being on this side of the Atlantic, but he should know it shouldn't be difficult to track down the story. If it was US CAS, the
PR types at CENTAF should be able to provide that info. Instead, his apparent efforts to prove it wasn't RAF Harriers involved seems to me, to miss the bigger picture.
To wit: SIX jets is the total CAS effort? And that commitment stretches the force? And sending a spare makes the news? YGBSM!
