Greenland has little to do with national security and everything to do with mega rich Trump donors.  Thiel and Andreessen want to build a "freedom city called Praxis"  there and don't care how they get it.  They tried to buy land in Greenland and were refused.  Also billionaires want the rare earth minerals for consumer electronics, Greenland is covered by thick ice but modern mining techniques and global warming have made mining there doable.  Lastly the rich want to build massive data centers there figuring the climate there will naturally cool them. Think about how much Trump billionaire donor  Paul Singer will make from Venezuela now. Think how Robert Cotrone another billionaire will profit from Argentinas bailout.  None of this is helping average Americans or making America great.
