None of these horrible things - this horrible murder case, all the other horrible murder and rape cases - would have happened if Merkel had just kept the border closed.
I understand you oppose that Merkel opened the borders for Syrian refugees, although I admire her for doing so (while oppose many of her policies).
While you may admire her for doing so, I think it is hard to look objectively look at where that decision has taken us and not characterize it as a failure, with the ripples threatening to tear the West apart.
America is part of “the West”, and Europe’s inhabitants aren’t tearing America apart.
"The West" is only meaningful as long as there is some degree of solidarity between its constituent nations. Clearly, that does not exist right now, and a strong argument could be made that what is going on in Europe only fanned the flames of Trumpism in the US.
