Imperialist history aside, can anyone cite contemporary documents indicating the current US govt wouldn’t be thrilled if PR decided to declare independence? As I understand it, the statehood issue never having traction in congress is because PR would be a new blue state with no potential red state to balance it.
This new state “balance” has been a problem since antebellum times. Most recently AK balanced HI. The only other potential new state is DC, also blue. You’d have to split a red state like TX in 2, or slice populous but regionally divided states like CA, NY or FL make a new red state. Downstate NY would LOVE to be cut free from Albany.
