No, you're wrong. It won't end any wars and it won't usher in an era of peace and democracy, but it will destroy the threat. Try harder with your straw man fallacies.
You think we should genocide all Sunnis in Iraq, to end the threat? Threat to who, anyways? You know ISIS is basically Assad and Turkey's ally, with close economic and strategic ties? And that Iran and Iraqi Shi'ites have marginalized Sunni political representation and regularly engage in ethnic cleansing by militias, driving many people to embrace ISIS as a lesser of two evils?
And that we've been fighting the same people for ten years already, doing nothing but creating the instability that allowed a group like ISIS to become what it is today?
Its just very difficult to see what the fucking point is here. Unless you are cheerleading for Americans to go back and occupy half of Iraq?
Why don't you volunteer yourself to be frontline infantry in the Iraqi army, if you believe its just. We'd love to see your live posting while actually fighting a war.
