I and others here don’t have the text in front of us that your question mentions. I’ll simply offer some thoughts.
I do not believe the US was justified in its invasion of Iraq. The claim that Saddam Hussein had large stockpiles of weapons of mass destruction turned out to be false. The allegations of that were exaggerated in order to justify gout to war. There was no hard evidence that the weapons existed.
The idea of a pre-emptive strike also was a poor justification for war. The US had never gone to war on that basis before. It put the US in the role of the aggressor nation in the conflict.
