A senior Trump aide has reignited global alarm after suggesting the United States could seize Greenland if it chose to. In blunt remarks, Stephen Miller argued that power - not international law - shapes global order, dismissing concerns over sovereignty and NATO unity. Denmark and several European allies have pushed back strongly, warning that any move against Greenland would shatter alliance principles. The comments come as Trump renews interest in Greenland’s strategic Arctic position and mineral wealth, fuelling fears of a new era of American imperial assertiveness.
