the only germany that can do something is old nrd lands (imo) and it's up to you to fix your shit. you are still a behemoth in europe and you dictate a lot of things in eu. there's 0 trust from me to you since we and other eastern europe countries have been fucked hard and sweet (economically) after soviet occupation ended by west (france, gb as well). to give you the latest exampled why i don't trust your gov is you ignored schengen and closed borders while dropping your migrants into our country, so get fucked. we can work with you if you pay your reparations fully back for invading poland. you managed to pay jewish elders in israel in euro for years, so don't be scared to take responsibilty for what you did in poland and show your honesty, neighbour.
