At the time of the war, I thought it was a great idea. Saddam was a dictator, we were democratic states, so we should get rid of him and free Iraq. Then they'd thank us for all the democracy and freedom.
Of course, I was 14 years old back then. I didn't know about the history of US/UK foreign policy in the region.
In particular I didn't know about how our governments spent the '80s arming and supporting Saddam against Iran, or how they wiped out half the country's civilian infrastructure including sewage and water treatment plants in 1991 for no discernible reason other than spite and because they could.
Or how they called for the Shia resistance to rise up against Saddam before simply standing at the Kuwaiti border and watching Saddam's forces wipe them out. Or how the economic sanctions in the 90s killed hundreds of thousands of innocent people, mostly children and the elderly.
Had I known these things, it would have become clear that neither the US nor UK governments cared one single iota about Iraqi lives and that the invasion and "re-building" of Iraq would be carried out with equal contempt for the people living there.
Looking back, the intentions of the people who masterminded the war ensured that it was always going to end up like this: Iraq in ruins, no better off than it was under Saddam and the sanctions. It was all just a total, senseless waste of human lives.
