Had an idea for Mount Rushmore.
I think the requirements for it should be changed so that America has a chance to build it. Usually what happens is Prussia will beeline Fascism and build it straight away, meaning they'll have it almost 100% of the time.
I think the simplest way would be to make it require Republic like the SOL does, but maybe it could also be moved to a tech that the AI doesn't always beeline for. I don't think Mount Rushmore is really associated with Fascism either.
I'd also like to propose a new first UHV for America:
1. Control Alaska, Hawaii, Cuba, San Juan, Panama, & the Philippines in/by 1930 AD
or
2. Control X amount of Sugar, Silk, Spices, & Tobacco or Control X amount of luxury resources in/by 1930.
I think either of those goals are more representative of American imperial ambitions than just conquering all of North America, and it forces you to go out and conquer/settle areas of the map that are underutilized, such as Alaska, Hawaii, and even the Panama Canal.
