If the limited goal of killing some terries took 20 years, that's a failure in my book. And the fact that the Taliban won (and they did) makes it pretty hard to see Afghanistan as a win. I think it might be our Vietnam...
And before we decided to kill Saddam, they were a key check on Iranian power in the region. So... why are we there in the first place? Bad intel. That's a loss...
Like Saddam, Gaddafi kept Libya under relative control. Now? How has "let them figure it out" worked for us so far? It was figured out, then "we came, we saw, he died." Is that better?
I know what we could do. We could have won in Afghanistan too. The question is what actually happened/happens.
Yes, Isis, the Islamist psychodrama that was only possible because we destabilized the region by removing or attempting to remove the strongmen in charge of their countries. There is no ISIS if we didn't kill Saddam. That's the best example of "we created that problem."
We did excellent work at the tactical level in all of your examples. But all of your examples are exactly what I'm referring to. The pre-US-involvement status quo was better than how we left it. We did a lot of good work for ultimately worthless (or in some cases counter-productive) endeavors.
I do appreciate the dialog.
