Former U.S. President Donald Trump expressed interest in purchasing Greenland from Denmark in 2019. His plan was never formalized, but it was based on historical precedent, as the U.S. had previously purchased territories like Alaska and the U.S. Virgin Islands.
Trump floated the idea of buying Greenland through diplomatic channels, arguing that it would be beneficial for both the U.S. and Denmark.
 Reports suggested that Trump considered offering Denmark a financial package or investment in Greenland's infrastructure.
He emphasized Greenland’s importance for U.S. military and economic interests, particularly due to its location in the Arctic and natural resources.
For that he is interested to take Greenland. One the other hand Russia is also to take Greenland.
