Vice President JD Vance joined his wife's trip to Greenland to focus on national security issues, particularly to assess the situation at the Pituffik Space Base.

Danish Prime Minister Mette Frederiksen described the U.S. actions as placing 'unacceptable pressure' on Greenland, while Greenland Prime Minister Múte Egede characterized the visit as 'highly aggressive'. Both leaders have rejected any idea of Greenland becoming part of the U.S.

The Trump administration views Greenland as strategically important for national security, particularly in deterring threats from Russia and China. President Trump continues to express interest in expanding U.S. influence in the region despite previous rejections.

Usha Vance's trip was initially planned as a cultural visit to explore Greenland's historical sites and attend the national dogsled race. However, with Vice President JD Vance joining, the focus shifted to national security and visiting the Pituffik Space Base.
