With Trump floating aggressive desires to acquire foreign territories like the Panama Canal, Greenland, and Canada, ambassador confirmations could get messy.

First it was Canada, then the Panama Canal. Now, Donald Trump again wants Greenland. The president-elect is renewing unsuccessful calls he made during his first term for the U.S. to buy Greenland from Denmark,

While Greenland is currently not for sale, the U.S. has purchased land and territories from other countries in the past.

Since his first term, President-elect Donald Trump has insisted that the United States should purchase Greenland - to the bewilderment of aides asked to investigate such a possibility, and despite repeated denials by top officials in Greenland and Denmark, of which the island is an autonomous territory, that it would ever be for sale at any price.

The mineral history of Greenland reveals that the United States could have a military presence and environmental security without acquiring the massive island.
