I don't want to sound dumb but what does Axis mean (I'm not a native English speaker)?
Although I don't know what it means, I think its' the most appropriate term. "Nazi" is too political, "Germans" is too unfriendly against the germans

and "the enemy" is just too stupid.
And I think the Netherlands or Canada are more lands of the free than the USA with all their bleeping and black rectangles.
Why do you need a gun anyway? Don't say "for protection" 'cause I feel more safe when nobody has a gun then when everybody has one. The police is for protection, the gun on your belts is for your ego.
