Donald Trump has again proposed annexing Greenland, after Denmark's leader urged him to "stop the threats" over the island. Speaking to reporters, the US president said "we need Greenland from the standpoint of national security". Trump has repeatedly raised the prospect of the semi-autonomous Danish territory becoming an annexed part of the US, citing its strategic location for defence purposes and mineral wealth. Greenland's Prime Minister Jens Frederik Nielsen responded by saying "that's enough now" and described the notion of US control over the island as a "fantasy".
