Sources please, otherwise this sounds like an usual BS propaganda. One real example to contradict - in WWII, Switzerland was accepting (not only jewish) refugees when completely surrounded by Nazis/their allies. We are talking about tiny landlocked country just to be clear. When it would became clear that country can no longer feed its citizens and more incoming refugees, they decided to close the borders("das boot ist voll"), and still one canton - Geneva - said fk you, and keep them coming. Even when it was clear its not sustainable.
