Even estimates can only get to 151,000 from the war.
Do you not believe people within a country have the “liberty” to determine what and how they handle themselves? What they chose to do, especially after 2011, was entirely up to them if here in the US after the war with England, our country’s independent colonies became states within a loosely defined republic. For Iraq, it chose to go back to warlords and insurgents. That probably says more about Muslim ways than anything else. After all, look at the evolution of Turkey to today.
Bush couldn't find Bin Laden, and the military industrial complex needed $$$, so the WMD predicate was used to throw us into a middle east quagmire for going on 20 years (hint - we're still pulling triggers in Iraq and Syria to this day). WMD, "War on Terror", "Support Our Troops", "Fight them over there, not over here" - all are tropes used to incite support for a really stupid war.
Full Disclosure - I personally supported it at the time. That was for the first 5-6 years. But we beat the Japanese and the Nazis in 4 years. Once we passed that mark, reality set in - we're not playing to win. Ten years in, I started asking "who benefits?" Now almost twenty years in, only a fool would not see the grim truth that money and power in the region (pipelines, oil fields, etc.) drives everything and our men and women in the military are ground up and spit out for no other reason than that.
Don't be a fool...
