There is probably going to be a fight for Greenland between the US, China, and Russia. I think it was the Chinese who already planted a flag at the bottom of the ocean, at the North Pole, using a submarine. With the North Pole melting, the geopolitical map is drastically changed. Trump probably wants it to be US land so he can sell tickets to watch the collapse of the planet's ecosystems.
Yea like 98% of the population wants statehood. If they brought something to the table it would be worth considering but as it stands there's just not enough good reason to ratify membership.
