I suspect there are more reasons than that. The EU didn't just open them in Germany. If Germany needed that manpower they could have just opened the German borders. Instead they are force (coercion is threat, and the EU is threatening those that do not comply) the EU members to open their borders.
I see it more as a combination of Kloward and Piven and the Hegalian Dialectic. Create the problem, so people will accept the solution you have in mind before the problem is even created.
The only thing going wrong in their plan. People noticed. People are resisting. So the propaganda machine is going full bore to silence the counter propaganda (aka Truth).
Thus the censorship all over the place, and thus the EU laws near passage that will destroy the internet for the EU. Likely to be adopted for some insane reason after their passage. Though I don't expect the EU citizens to remain peaceful towards their EU overlords if it happens.
I was talking about Germany specifically but yea I agree the gran plan is to control the whole europe this time without the tanks...
I believe that ww2 never ended it just went underground...
It is a slow and silent fight let's hope for the best!
