Yeah, they've been there. A huge contingent, no? And their contributions compared to the size and wealth of their country are also huge. But let's be grateful, after all. They spend about 1% of their GNP on national defense, and kept hundreds of thousands of soldiers in the US during the Cold War so that the Soviets would not invade.
That's the spirit! Complain, complain, complain. Complain when the Germans help, and complain when they don't. When they get tired of hearing you complain, and quit helping altogether, complain even more loudly.
