Danny,
I wouldn't worry overmuch about political correctness. I never experienced a great deal of that during my time in service, as Hangarshuffle says quite well, unless I have misunderstood him, the whole shebang is the result of weak indecisive political leadership, allowing themselves to be driven by their sad need for popularity. Like you, I doubt that "tinkering" from the air will do anything to affect the outcome on the ground, and eventually a serious move, on the ground will be required to eliminate the ISIS plague. It's just a matter of how many innocents the likes of Obama and Camoron are prepared to sacrifice for their summer hols and ineffectual leadership. I also wonder how long before their sympathisers in Britain begin to emulate their heroes in our own country, a la Lee Rigby, the great multicultural experiment has certainly put a Trojan horse in our midst.
