Do you suppose Trump wants Greenland to use as

5. Highly Impractical.

1. There are no existing facility for such detention.
2. We don't have Greenland.
3. If we got Greenland, it would take a lot of time and money to build the facilities needed.
4. It's freaking cold in Greenland, and there's ice everywhere. All year.
5. Transporting building materials, etc. would cost a fortune. There's nothing in Greenland to build it with.
5. The cost of transporting thousands of detainees would be prohibitive.
6. The cost of supplying a facility that could house them would also be horribly expensive.

Impractical. I would take at least 2 years to even be ready for detainees, if we even had Greenland.
