Mate Imperial Germany was too fucking dumb to help itself. Do you know the story of the Zimmerman Telegram, when those dumb German bastards used a Telegraph line the US gave them access to (their own lines had been cut by the British), to try and arrange for Mexico to go to war with the US. The US didn't really want to join the war the fucking Germans made them.
Same thing happened in August 1914 with the UK. There was a British government in power that would have happily stayed out of the war, if only Germany hadn't invaded Belgium. Ignore fucking Dan Carlin, imperial Germany was a blight on the world, and if they had won, would have ended up in a war with the US within a few years (because that was German thinking, fight wars sooner rather than later)
