Reykjavik describes the social media post as “completely inappropriate” after Trump shared a map depicting Iceland, Greenland, Canada, Mexico and the Caribbean as part of the United States.

Iceland has summoned the United States ambassador following a social media post by President Donald Trump depicting Iceland and several other countries and territories under the American flag.

The move came after Trump shared an image on his Truth Social account showing the United States, Canada, Greenland, Iceland, Mexico, Central America and the Caribbean covered by the US flag.

The entire landmass shown on the map was labelled “United States of America.”

Trump posted the image without an accompanying explanation, prompting concern in Iceland and an immediate diplomatic response from Reykjavik.

Iceland’s Foreign Minister, Thorgerdur Gunnarsdottir, summoned US Ambassador to Iceland Billy Long on Monday to discuss the post, according to Icelandic broadcaster RUV.

Long formally took up his post in Iceland only last month.

The Icelandic Foreign Ministry told RUV that its position had been clearly communicated to the ambassador.

“The position was clearly expressed that the post was completely inappropriate,” the ministry said.

The diplomatic summons underscores the sensitivity surrounding territorial sovereignty and US relations with countries and territories in the North Atlantic and the wider Western Hemisphere.

Trump’s post did not state whether the map was intended as a political statement, a joke or a reference to any specific US policy. However, its depiction of Iceland and other independent countries and territories as part of the United States quickly drew attention in Reykjavik.

The development also comes amid heightened international attention to Trump’s interest in territorial issues, particularly Greenland, the autonomous territory of Denmark.

Trump has previously expressed interest in acquiring Greenland, arguing that the Arctic territory is strategically important to US national security. Denmark and Greenland have repeatedly rejected the idea of transferring sovereignty to the United States.

Iceland, an independent Nordic republic and member of NATO, maintains close security and economic ties with the United States. The two countries have also historically cooperated on North Atlantic security.

The latest incident, however, has introduced a diplomatic controversy over a social media image that Icelandic authorities considered inappropriate.

The US State Department, as well as US embassies in Copenhagen and Reykjavik and the US consulate in Nuuk, did not immediately respond to requests for comment.

The Icelandic Foreign Ministry also did not immediately respond to a separate request for comment.

For now, there is no indication that Trump’s post represents a formal change in US policy toward Iceland or any of the other countries and territories shown on the map.
