The post is not apologia and not making light of his crimes. The post is saying there was no one who had leverage on him such that they could force him to do all the stupid shit he did. He just invaded a country and kicked off multiple decades of war in the Middle East for no comprehensible reason, like compromat. In the absence of a "mitigating reason" (as much as you can mitigate "war crimes"), it makes his actions look even worse

I had never heard of W gaining direct financial compensation from going to war. Oiling the US war machine doesn't directly benefit many politicians; it just hoes the farmbed to ensure a healthy crop of corruption keeps growing.
