I've seen the Civil War thread and I think this could also be a good idea.
I'd say MacArthur as the "American Führer"
Post your b̶e̶s̶t̶ worst clichés
-There will be at least two events analogous to OTL's World Wars
-Austria Hungary always performs poorly, even if the dumpster fire that was the lead up to the battle of Galicia shouldn't be replicated by default
-If the CP is victorious Austria-Hungary will still magically explode cuz muh nationalism (ditto Ottomans)
-the KKK will unanimously be Nazi collaborators
-Italy's performance in WWII is dismal regardless of circumstance
-If Italy stays out of WWII it's forming a fashy NATO/Warsaw Pact analog
-The Democrats will always leap frog the Republicans to become America's "left wing" party
-South Vietnam is doomed, and any surviving South Vietnam would have been better off had it capitulated to the North
or
-a surviving South Vietnam becomes an Asian Tiger and is a liberal democracy by the 2000s
-Yugoslavia will be neutral, regardless of the situation (even though it wasn't all that neutral otl)
-Obama will still be the first not white president of the USA
-post-colonial Africa will still be generally quite bad, unless not!Ian Smith or not!Thomas Sankara comes to power in their country and turns that country in to a [pick your flavour of politics] wingnut's fantasy realm
-Any Iran that goes through the revolution will inevitably become the centre of the axis of evil
