Its because you are all evil I tell you!"
It's not evil, you see, it's... frustration. You have to let out all that pent up warrior aggression some how. In Sweden's case, it's done by throwing IKEA and Metal music at people around the world, producing top notch savage weaponry and running around the world in every possible peace keeping mission sanctioned by the UN. Denmark and Norway are domesticated war addicts as well. Scandinavia have been in almost constant war since... ALWAYS! Sweden went cold turkey from serious warfare after 1814, when it invaded Norway. After that... nothing. Denmark and Norway were occupied during WW2, so they are bit extra pissed about that, I guess. It's better for the world with some mad/evil scientists than letting loose a bunch of rabid Viking ancestors in full scale warfare.
Dunno about northern Europe (Germany). Maybe they lack self control.
