The Deutsches Übergangsregierung condemns the German invasion of Hamburg. The city of Hamburg was made a sovereign nation, created by the nations of Denmark and the United Kingdom. The invasion is unlawful, which creates another reason for all nations to despise the Communist scum.
So when did I invade Hamburg? British troops left Hamburg, the citizens of Hamburg took control themselves and declared themselves part of DDR. Due to this the DDR talked to Denmark and the UK and then - after having informed both nations and having made sure it is no hostile action- moved troops into the city, restoring public order, guaranteeing the safety of every foreign citizen and therefor ensured a peaceful solution. Explain how this can be called an invasion.
But ok, let's take it as diplomatic intentional spreading of false information then.
