The Austrian Painter's 75th Birthday: What are the Yanks up to?

So let's say the Great War never happens, or more precisely Germany knocks out France in 1914 and Russia in 1915. We flash forward to our protagonist's 75th birthday in 1964. What's the United States been doing this whole time?

There is still a war with Japan at some point. It was inevitable. Perhaps that war is closer to Hector Bywater's The Pacific War, a piece of Clancyesque alternate history written in the 20's.  Does this Pacific War go to the hilt? Or is it a series of wars that flair up every decade?

With no Great War there's no Isolationist reaction, but America probably still sees little reason to get involved in Europe.

Domestically in this 1964 we'll still see social change. Technology is still marching on. A woman's kitchen has been overtaken by gadgets and she's probably wondering why be at home. The Civil Rights movement is still in full swing. Still, there's no 1960's as we think of our own.

There's also no Cold War. That means no space race. We don't think we've seen the invention of atomic weapons yet.

One of the questions we've been dealing with is the Great Depression. Does it still happen? Roughly, we can say that mechanization will occur, leading to a drop in farm prices leading to a farm crisis. Stocks are still being bought on margin. There will most definitely be some sort of economic calamity, but will it be closer to 2008 than 1929? All lot of other things had to go wrong for the Crash of '29 to turn into the Great Depression.

Overall, in The Austrian Painter's world the United States is still very inward looking and lacks the post war dynamism that exited in our own 1964.
