After two centuries of non-alignment and two years of torturous diplomacy, Sweden on Thursday, March 7, 2024, becomes the 32nd member of NATO, a major step for a country once careful not to anger Russia.

Swedish Prime Minister Ulf Kristersson was visiting Washington where Secretary of State Antony Blinken will ceremonially receive the ratification documents after the hard-fought battle to secure the green lights needed from all NATO members.

Kristersson is likely later in the day to attend the annual State of the Union address by President Joe Biden, who has been struggling to persuade the rival Republican Party to approve new aid to Ukraine.

Sweden’s blue and golden-yellow flag is expected to be hoisted on Monday at the Brussels headquarters of the North Atlantic Treaty Alliance.

Russia has vowed “countermeasures” over Sweden’s entry into NATO, especially if the alliance’s troops and assets deploy in the country.

Sweden and Finland, while both militarily intertwined with the United States and members of the European Union, have historically steered clear of officially joining NATO, formed in the Cold War to unite against the Soviet Union.
