Whoaa....
You're talking about a diplomatic defeat, what Germany was left with after they'd already made peace. Very different thing.
It was a very different story on the ground before the armistice. Their army was very short of food & supplies, but was still largely intact in places, and the High Seas Fleet was still a match for the Royal Navy, until German sailors scuttled it.
The military situation in 1918 was very different to that in 1945.
But this is for the History forum, so...
This is complete crap do not post nazi stab in the back propoganda on this forum, thank you.
