Okay I have an idea with a rough tl in my head. Basically WW1 is fought with America on the Central powers side. The war ends in 1919 Europe with a Entente victory but America stands victorious in the Americas, occuping Canada and possibly some Caribean islands. How do you think the world would develop? The Europeans are dead exhausted, Russia is in civil war, Germany is possibly as well. If America decides to prosecute the war how would they go about doing it? More likely I think a cold war would develop with a tenuous cease fire. Would America invest in Goddard and push Rocket(and by effect space travel) technology 10, 20, maybe 30 years ahead of its time?
