"Polish Prime Minister Donald Tusk said Poland was not planning to join the European military deployment to Greenland, but warned that any US military intervention there "would be a political disaster". "A conflict or attempted annexation of the territory of a NATO member by another Nato member would be the end of the world as we know it - and which for many years guaranteed our security," he told a press conference. Russia's embassy in Belgium meanwhile expressed "serious concern" at what was unfolding in the Arctic, accusing NATO of building up a military presence there "under the false pretext of a growing threat from Moscow and Beijing". However, the European NATO deployment consists of only a few dozen personnel as part of Danish-led joint exercises called Operation Arctic Endurance. While heavy in symbolism, it was not immediately clear how long they would stay. Germany was sending an A400M transport plane to Nuuk on Thursday with a contingent of 13 soldiers, although officials said they would stay in Greenland only until Saturday. Danish defence officials said they had decided with the government of Greenland that there would be an increased military presence around Greenland in the coming period to bolster Nato's "footprint in the Arctic for the benefit of both European and transatlantic security"."
