The Whole World In Your Hands

Germany, eh? Goin' for the big one. This will be tough, but with the right offensive it could work. And after Germany they'll all drop like flies! It's time to plan. You could go in with an all-out offensive and hope the rest of the world doesn't notice, then kill everyone else, or you just try to nuke the hell out of the Germans. But that might lead to nuclear war. And that wouldn't be pretty.

Or, you could get sneaky...and beat them through diplomacy. But that would be tough, as Germany is much more popular throughout the world than the United States. You could accuse them of neo-Nazism and sentence obliteration as punishment. What's the plan?
