No real shock. There’s been comments by the Bavarian state government that they’d go on their own....without the Berlin leadership approving it, and build the fence. If they did that....it’d open big issues across the nation.
I will say this....having been stationed in Germany during the cold war period....the fence idea barely gets you to first base....you end having to put land-mines out to really hamper people crossing. The public will not be happy when they discover there’s another step in the process.
And...fences and minefields only work if they are overwatched and patrolled regularly.
