Can a nation possess another nation?

No. That is colonialism, and it is considered a crime against humanity.

Click on the following link to watch a video about Puerto Rico being a colony of the United States (US) government (USG) for the past 122 years: https://youtu.be/n9L35g9lCtE

The only problem that I have with this video is that it said that Puerto Rico was a colony of Spain at the time of the US military invasion. Puerto Rico was, in fact, a Spanish province.

The United Nations’ Charter prohibits colonialism since 1945. Since the USG has never complied with the US Charter for the past 76 years, the UN has issued 39 resolutions asking it to immediately return Puerto Rico’s sovereignty to the Puerto Ricans. Thus, the USG is a criminal! Moreover, the world regards the USG as the biggest threat to peace! http://webtv.un.org/watch/5th-meeting-committee-of-24-special-committee-on-decolonization/6051725003001/  

Most Puerto Ricans has tried to fight colonialism within the framework of the USG. That would never be possible, since the USG is the problem. We must fight for our decolonization via international law. That international law is in our favor!

We must, therefore, engage in permanent resistance to force the USG to comply with international law. Imagine almost 9 million Puerto Ricans worldwide protesting in the streets for our inalienable right to self-determination and independence. www.TodosUnidosDescolonizarPR.blogspot.com
