I'm talking about most of Washington DC and other landmarks that are symbols of the USA. What do you think should happen to them? Mostly kept around or mostly destroyed?
Things like statues (unless they are actually old or have historical worth) probably can go, buildings can probably stay.
For Colorado being the capitol, if rumors and conspiracies are true then the Colorado Airport is already suited to be transformed into some form of seat of power, and theres already other airports nearby so you can just repurpose it.
