I'd love to hear an argument for this being true that doesn't involve counting all of the deaths caused by Sunni-Shia sectarian violence in Iraq, suicide bombings in civilian markets, ISIS etc. as caused by America.
Well there's Vietnam, Afghanistan, Syria, Yemen, Libya etc which would tally ~300k civilian deaths alone. Given the blatantly false pretences that America invaded Iraq under, and the sectarian violence that significantly flared post-Saddam, I don't see why you'd not want to involve Iraq in the stats?
I accept US responsibility for a great many of the civilian deaths caused in Vietnam. I don't accept US responsibility for Islamists of different varieties blowing up each other's markets and places of worship with weapons provided by Iran and Syria.
So you don't accept the fact that a lot of this sectarian violence flared after the toppling of Saddam, which was because of the US? And how many of the deaths do you attribute to the sectarian violence, as opposed to the direct actions of the US in the region?
You might be into that. The rest of us like to analyse things honestly, especially given America is going down the route of making the same moves as history. If you don't see that, then it'd probably be better for you to go read something than to offer pithy comments on here.
