I'm not sure if the post major combat decisions were the only problem. That obviously was a major part of what happened. But a major issue appears to be that we simply didn't have the resources to really handle two wars at once. And it seems that even with the bad management decisions made in Iraq, the Iraqi people were not nearly as willing to cooperate with the US or ready to establish democracy as I thought. The complete and utter absence of WMDs also made a major argument for the war completely incorrect.
It is possible that with much more careful decision making things might have turned out very differently. It is in general difficult in any complicated situation to pick any specific thing and say "but for that, things would have gone well". Even if the main cause was post-invasion decisions, the bottom line is that people like me implicitly trusted our armies and politicians to make good decisions in that context and they didn't.
There's another issue that also doesn't come up much: there's a certain fraction of the population which wasn't in favor of the Iraq war, and they like saying "I told you so" but in fact they didn't. Most of their argument was meaningless slogans. Iraq wasn't about blood for oil. And there wasn't an intrinsic moral problem with it. Some of the people against the war expressed worry about a Vietnam type situation, but even then that's not what happened. What has gone wrong in Iraq has only a superficial resemblance to what went wrong in Vietnam. I almost want to shout at those people "look! With all the motivated cognition that was happening why couldn't you actually hit on what actually might happen?" But that may be simply due to an emotional need to feel like things aren't completely the fault of people like me.

I suggest evaluating a point of view by its best proponents, not its worst or even its average proponents.
Andrew Rilstone got a lot right, ten years ago:
...But a general war against terrorism – or, in some views, against evil in general – seems too open ended. It could go on forever. Millions could di

This article may have more political content than is suitable for LW-- if you'd rather discuss it elsewhere, I've linked it at my blog. I've posted about it here because it's an excellent example of updating and of recognizing motivated cognition even if well after the fact.
