Germany has an army.
USE IT.
Surely you jest. Merkel is welcoming them with open arms, she said they made Germany stronger as a nation. I guess because more people are in the mood to fight? I predict in the not too distant future that real fighting will erupt over there. Totally insane what that woman is doing to her country.
The German Army is around 50k. Actual combat ready troops are much less. The whole country is about to become sitting ducks. Even if all is peaceful numbers like that would bankrupt the country.
