Yeah, at first thought, this seems right in cheeto's wheelhouse of stupid shit to say.
I watched a CNN interview tonight with the author of the article in the link, Vivian Salama.
Apparently lard ass, is not alone in this thought, nor the first.
Vivian Salama said that two other times, the US wanted to buy Greenland (from Denmark)
Once in the 1800's and the second time, after WWII. She said that after WWII, the Truman and the US
offered 100M for Greenland.
In the 1800's, the US did try to buy Iceland from the Danes in
the 1860's which would have included Greenland.

Refer to pages 5-6
"In the summer of 1867, while Seward was negotiating with the Danes, a former Secretary of the Treasury, Robert J. Walker,
now an influential Washington lawyer, suggested to him that Greenland, and possibly Iceland, should also be bought from Denmark. "
" After much delay, in 1870 it was finally rejected by the Senate. Secretary Seward realized that in the circumstances the idea of acquiring Greenland and Iceland could hardly be pursued any further (Dyer, 1940).However, it should be noted that if the United States had purchased Iceland at the sameprice per square kilometre as Alaska, the total price would have been equivalent today to 6.2 million U.S. dollars, remarkably close to the prices for Iceland, thrown around in 1518 and 1645 (Gissurarson, 2015) "
