Why not PR too?

Why don't nations call for Puerto Rico to also be included in the international system?

Puerto Rico has been a United States (US) colony for the past 127 years. The US has, thus far, ignored 43 United Nations resolutions demanding the immediate return of Puerto Rico's sovereignty to the Puerto Ricans. In the meantime, 6 million Puerto Ricans have abandoned their national territory (gentrification), and about half of the 3 million people in Puerto Rico today live in poverty.

The US, however, has the audacity to deceptively claim to support Taiwan's inalienable right to self-determination and independence, only because it wants to try to justify going to war against the People's Republic of China to colonize her too.

Why not justice for all?
