After long negotiations, Sweden officially becomes the 32nd member of NATO this Thursday. Swedish Prime Minister Ulf Kristersson is traveling to Washington, where the head of American diplomacy Antony Blinken is to officially receive the ratification documents.

The blue and yellow Swedish flag must be raised on Monday in front of NATO headquarters in Brussels. Russia promised last week to take “countermeasures” in reaction to Stockholm's accession, which will depend “on the conditions and extent of Sweden's integration into NATO”
