The German government wouldn't have had these issues if they didn't poison their own people...

The German government haven't been the "own people" of the german populace since the 1940s. They've been an occupied nation, with foreigners that hate them in positions of power who've been forcing down this poison.

This isn't some accident or miscalculation. They aren't trying to make the world a better place. They know they're making it worse and they know it's a genocide. It is exactly what they've been hoping to achieve for 100+ years.
