Silly question. Everyone knows it was the Jews:
In the 1960s, President John Kennedy decided to establish governmental banks to protect the dollar, in which the gold that was pouring into America would be deposited. What became of Kennedy? He was killed by the Zionist lobby. This is a fact that nobody is aware of – but a fact it is. That was the reason Kennedy was killed.

And yet we wonder why Middle Eastern society is so screwed up.
