Iceland Summons US Ambassador Over Trump Map Depicting Territorial Expansion

On September 7, 2026, U.S. President Donald Trump sparked a diplomatic incident by posting an uncaptioned map on Truth Social showing the American flag covering Canada, Mexico, Greenland, and Iceland, labeled as the "United States of America." In response, Icelandic Foreign Minister Thorgerdur Katrin Gunnarsdottir summoned U.S. Ambassador Billy Long to deliver a formal rebuke, labeling the post "completely inappropriate." The incident follows a pattern of territorial rhetoric from the Trump administration, including repeated interests in Greenland and trade tensions with Canada, and comes shortly after Icelanders voted against reopening EU accession talks.

// Background

Relations between the U.S. and North Atlantic states have been strained by President Trump's recurring interest in acquiring Greenland and his "maximalist" rhetoric regarding neighboring territories. Iceland, a NATO member without its own military, relies on a 1951 defense agreement with the U.S. but has recently seen internal debate over EU membership as a hedge against geopolitical instability. Ambassador Billy Long, who took his post in August 2026, had previously apologized for joking about making Iceland the 52nd U.S. state.
