I just checked Visegard, which has up to date news from the Poland/Belarus situation. Germany has now announced they will not take any “migrants”, and one flight full of Iraqis has already gone back from Belarus to Irag.
Latvia and Lithuania are guarding their borders and refuse to take any “migrants, and Hungary as well. The former Eastern Bloc is adamant and with no way to get through, and Germany refusing, I think the attempted invasion will sputter out pretty soon. Poland has been using water cannons and no one is getting through, a few groups that managed were put back to the Belarus side.
Great news.
