WWII in Europe ended not just with the fall of Berlin, but with the Marshall plan. If something like that happened after WWI, Europe would have been very different.

But enacting a Marshall plan requires a definite military defeat first. Else it's pacifying the aggressor again, with the same efficacy as in 1938.

How about preventing WW2 entirely? Hitler wouldn't have risen to power if Germany wasn't in tatters.

Exactly. A Marshall plan after WWI could be great.

Preventing WWI is a different matter entirely though. It was a very bloody lesson that seriously changes Western mentality; I suspect quite some reasons from 2022 just would not be understood in 1912.
