One person getting through does not a broken screening process make.
I think the main point would be why and how Germany can still largely keep the humanitarian policy after the current pressure today.
My guess is it's all about economic modelling as well as risk-benefit analysis, with a long-term and systemic view.
The decision highly likely must be made logically due to this long-term and systemic view is analytically and humanely better than other short-term and local-optimisation views, after considering political and cultural factors.
Perhaps we need to ask if even the US doesn't have the self-confidence, screening-protocol, settlement-capability and transformation-system for accepting new migrants, which country would have?
Then is the whole world so weak/powerless to do anything, or so blind to see/understand anything?
