Germany surrendered and signed the Armistice only when the Allied blockade had starved the country into submission.
Helped of course by the fact that the Germans had sharply denuded their agricultural sector by taking men off to the fronts.
The Germans over-threw the Kaiser ending the monarchy. This was after the allies distributed Wilsons 14 points (of a peace agreement) in Germany using aircraft
One promise was :”3.The removal, of all economic barriers and the establishment of equality of trade conditions among all the nations consenting to the peace and associating themselves for its maintenance.”
Of course once the Germans decided to give in the Allies set the state for Hitler and WWII with reparations(money Germany didnt have) , which Stalin repeated on East Germany in the late 1940s.
