Poverty doesn't cause terrorism. Islam causes terrorism.
The only thing the Arabs have created for themselves in the past 50 years is a terrorist infrastructure that uses a bogus "palistinian refugee crisis" to feed the hate that puts the "islamic charity" donations in the pockets of the terrorist organizers. The last thing they'll allow is is peace.
Furthermore, Islam, with its toxic concepts of post death X rated sex parties, redemtion through Jihad, its ultra violent Profet, etc is uniquely suited to brew generations of terrorists.
Islam also causes poverty. I am not saying this in jest. It is true. I have seen Islamic brodcasts dealing with exactly this point.
