Israel? Mid East/Arab troubles all down to them?

Strikes me as strange that people think so. Whatever your opinions regarding the israel-palestine issue, what have they to do with: The islamic revolution in iran 1979. the iran-iraq war, iraq's invasion of kuwait, civil war in yemen, civil war in algeria, darfur, civil war in south sudan,rise of baathism(neo fascism) in iraq & syria, civil war in western sahara, kurds war with turkey etc? Nothing Methinks!!
