shafique , here's how it was explained to me by a freind years ago:
They'll definitely stab you in the back in Europe; when a German does it he will explain to you in detail of why it had to be done; when the Frenchman stabs you, he'll cry a sea of tears with you!
But the Brit will say "Knife? What knife??"
I always thought that summed it up pretty well
PS: I presume he was talking about the "real" Brits, the white ones
