I don't mean to sound glib, but the 2003 invasion of Iraq probably is a much bigger reason for the continued unrest in that country. Syria isn't listed as using leaded gasoline, nor are Lebanon, Palestine, Israel, Bahrain, Libya or Tunisia, and yet all of these have some degree of unrest/instability/violence/civil war.
