I should have thought the loyalty of James Bond would depend on the character, rather than whether the actor is English or Scottish. Bond has some considerable Scottish roots. I think he was born in Scotland and attended, inter alia, Fettes School. There is a strong case for saying that he will, in future, work for Scotland.
This is bound to have a retrogade effect on the films. The tag lines (You've had your six, I think he's got the point, and so on) will go and be replaced by the ubiquitous "Who d'ye think your staring at? D'ye wanna fight?" There will be none of this poncy Martini stuff. Bond will be falling into bars in Ho Chi Minh City demanding a pint of heavy with a whisky chaser.
BTW, Flocc, that's not the whole of the Luxembourg Army. There's a bloke on a horse as well, who is the cavalry. They did buy a tank but they can't start it. They sent for a mechanic from France, but he hasn't turned up yet.
