The presidents of Latvia, Lithuania, and Poland — Egils Levits, Gitanas Nauseda, and Andrzej Duda — have sent a joint letter to NATO Secretary General Jens Stoltenberg and leaders of NATO member states to warn them of the threats posed by the developments in Belarus, BNS reports. In the letter, the three presidents pointed out that cooperation between Russia and Belarus undermined the security of the region and the entire Euro-Atlantic area. They noted that Russia had been using Belarusian territory in the war of aggression against Ukraine, specifically citing Russia’s deployment of tactical nuclear weapons in Belarus. Moreover, they warned that the relocation of Russian private military company Wagner Group to Belarus could "generate risks for the political stability in Belarus" and serve as an incentive for Belarus to trigger a new wave of irregular migration on the EU’s eastern borders.
