US and Denmark agree expanded Greenland security role
The United States and Denmark reached an Arctic security agreement that would expand the American military presence in Greenland while preserving Danish and Greenlandic sovereignty. President Donald Trump described the deal as permanent US control over security, though Danish officials had not confirmed all details. The agreement still required parliamentary approval.
Why it matters
The accord gives Washington a larger Arctic role without delivering the ownership of Greenland that Trump had previously sought.
