In 2019, a proposal by Trump to buy the world's largest island, Greenland, brought great debate in the press and in political circles.
According to some experts, this was a strategic decision by the American president, given that the island was also attracting China's attention. But for Trump's Democratic opponents, it was just another of his gaffes.
Recently, two American journalists, Peter Baker of the "New York Times" and Susan Glasser of "The New Yorker", wrote that it was a friend of Trump's who pushed him to ask to buy the island.
Ronald Lauder, Trump's friend and President of the World Jewish Congress, was the person who suggested to the former president the purchase of the island from Denmark.
As soon as this idea was articulated, the reaction of Denmark was immediate, describing it as an absurd idea and that the island was not for sale.
The debate remains open as to whether it was a well thought out strategic decision or a spur of the moment decision. The American-Jewish businessman Ronald Lauder has also served as Trump's adviser to solve some of the problems in the Middle East.
Lauder was one of the prominent figures who advised Trump on how to resolve the Israeli-Palestinian conflict, urging him to invest in serious negotiations that would lead to the creation of a Palestinian state.
America has bought territories from other countries before. In 1803, Thomas Jefferson bought Louisiana from France for $15 million.
In 1867, Andrew Johnson paid $7.2 million for Alaska from Russia. The territory was also bought by Denmark. In 1917 Woodrow Wilson bought the Virgin Islands for $25 million.
