Iceland summoned U.S. Ambassador Billy Long on Monday after President Donald Trump posted a map on Truth Social depicting the Nordic nation, along with Canada, Greenland, Mexico, Central America, and the Caribbean, covered by the American flag and labeled as part of the "United States of America."

The post, made without any accompanying text or explanation, prompted Iceland's Foreign Minister Þorgerður Katrín Gunnarsdóttir to call in Long for a formal meeting. The ministry stated that officials made clear the image was "completely inappropriate." Long, who formally assumed the post last month, received the rebuke hours after the map appeared online.

Icelandic Prime Minister Kristrún Frostadóttir described the map as "ridiculous" during a Tuesday press conference and called it an insult to Icelanders and their neighbors. She emphasized that joking about the sovereignty of states is neither funny nor normal, particularly in the current geopolitical climate.

The incident builds on existing tensions stemming from Trump's repeated expressions of interest in acquiring Greenland, a Danish autonomous territory, for U.S. national security reasons. Earlier this year, Long himself drew criticism after joking about Iceland potentially becoming the "52nd state," for which he later apologized.

Trump's map post aligns with his broader focus on strengthening American influence in the Arctic region. The image appeared the same day European Commission President Ursula von der Leyen visited Greenland to announce a €200 million investment package.

Danish Prime Minister Mette Frederiksen also weighed in, noting that Greenland's government and people have consistently rejected external control. Icelandic officials have stressed the need to take Trump's statements seriously, even if not literally, reflecting ongoing diplomatic friction between the allies despite shared NATO membership.

No U.S. officials have commented on the specific post or the summons. This episode is the latest in a record of controversial White House social media activity designed to generate swift online reactions.
