Johny Foreigner and the Spirit of the Blitz (Reversed)

Strange how we are so often told that the Blitz brought out the best in the British, how we refused to be cowed in the face of air attack on these islands, yet our Middle East policy is now - apparently - based on the total opposite. Could it be that Cameron actually believes, as per Mainwaring/Jones, that IS 'don't like it up 'em'? That, contrary to how the Brits took it on the chin from the Luftwaffe, that the assorted nasties ranged against us will crumble at the first rumble of RAF bombing? When Kenny Everett (yes, he was a Tory supporter, don't forget) put on his 'bomb the bastards' personna he was joking. But Cameron/Fallon and crew seem to have missed the punchline and enshrined the principle into foreign and 'defence' policy...
