Israel's existence doesn't cause too much turmoil.
The suggestion seems to be that if Israel weren't there, turmoil would be less. I see no evidence to support that claim.
There are about 26 conflicts going on in the world.
1 involves Israel.
22 involve Moslem states or populations.
Israel has nothing to do with Sunni and Shia slaughtering one another, Christians, and Sufis and Hindus on occasion.
Israel has nothing to do with Iran threatening her gulf neighbors and claiming them as their property since Iran is heir to the Persian empire.
It has nothing to do with Syria killing about 30,000-40,000 citizens in one weekend or Jordan killing about 10,000 Palestinian Arabs in a month over disagreements.
Christians were free to live and practice their religion in Bethlehem and Nazareth UNTIL Israel turned it over the PA and Hamas. Now, there is ethnic cleansing, kidnappings and forced conversions, murder, torture, and sexual assault rampant.
