Should Greenland exist independently as they cannot defend their island?

Should Greenland be allowed to exist independently? They are not able to defend themselves. They live on a huge island that is strategic for the safety of half of the world. Denmark cannot defend themselves either, much less Greenland. Should Greenland become a US state and prosper while securing their future and the world’s safety? 50,000 people is barely a decent side US town.
