The caveat is that there's almost nobody in Germany who'd be physically fit and or motivated to actually fight a war. Germany was systematically drained off anything even remotely resembling patriotism. This was politically and legally enforced by borderline criminalizing terms like Heimat (home / homeland), forget about displaying its flag without raising eyebrows. Its cultural DNA is diluted to an extent that I'd be hesitant to even call it a country - it's basically just an area with lots of people living on it. There's no coherent society anymore. The war machines will all be sold to other countries. Rich people will get richer and the plebs will be brought to heel with orchestrated fear. It's a funny irony that the warmongers in German politics are the same people who'd have taken any opportunity to express their contempt for anything military up until only a few years ago.
