Because there is no substance. But I'll respond anyway. By the statistics, the top sources of immigration to France historically are: Algeria, Morocco, Tunisia, Portugal, Italy, Turkey. Please explain how US foreign aid to Israel destabilized these countries. Even if you're talking about refugees from Syria via Turkey, blaming American aid to Israel for the Syrian civil war is historically illiterate. So, back to my original statement: your brain has been poisoned. Please seek immediate medical attention.
That’s not a rebuttal or argument. No attempt to address the substance. But I’ve come to expect that.
