The USA has signed a new defence agreement with Denmark and Greenland, allowing Washington to establish two additional military bases in Greenland while reaffirming Danish sovereignty and Greenlandic self-determination. The agreement, updating a 1951 defence pact, permits two new US facilities, although operational details require agreement between all three parties. Washington may also expand its existing Pituffik space base. The accord prevents non-NATO countries from maintaining military installations, and confirms that Greenland would remain within NATO if it eventually became independent from Denmark. Donald Trump described the agreement as strengthening security, and Danish prime minister Mette Frederiksen emphasised respect for sovereignty and territorial integrity. Greenland’s PM Jens-Frederik Nielsen welcomed his country’s involvement in negotiating the agreement. The deal follows months of tension after Trump repeatedly suggested purchasing or annexing the strategically important Arctic territory.
