Why is Argentina reigniting the Falklands dispute?

President Javier Milei has stated that sovereignty over the Falkland Islands remains a national objective. The dispute between Argentina and the United Kingdom has been reignited by a British-Israeli oil exploration project, which Buenos Aires vehemently opposes. Milei has threatened to sanction companies operating in the area, bolstered by comments from U.S. President Donald Trump regarding Washington's position on the territory.
