I can imagine what the Founding Fathers would say about “liberating” PR from Spain in order to colonize it.
This is a shameless land grab by brute force like the annexation of Hawaii.
PR should be given independence like Panama, Cuba and the Philippines.
If we give PR independence, they will likely soon be under the thum of Cuba, Veneuela, and Putin. If a majority of people in PR actually vote for independence then we should give. Fortunately, such a vote is extremely unlikely.
