I'm german and I absolutely disagree with these measures. It goes against all our Union within Europe stands for. We have to solve issues together not everyone on its own.
If there is a problem, we have to strengthen the EU-outside borders not the one within.
I would wish a better support and cooperation for countries with EU borders. The budget and people for strengthening german borders should go to an EU wide border cooperative that protects the EU outside borders together.
But it seems a lot of people are listening to the tribal/populist siren song of AfD. I hope you guys can get that straightened out, and soon. I know the former GDR tends to be very fertile ground for that sort of rhetoric for a variety of reasons, so from where I’m standing, trying to address the root causes there is probably going to yield the best long term results.
I think that it's better than German doing a UK and exiting the EU or Schengen or something, if that's at risk.
I am skeptical that if that kind of political risk doesn't exist, that it's a win, though. It's going to increase transport costs and make it harder for businesses near the border to operate.
