I generally agree with you on the mistake in all American interference in foreign lands when they do it. I think it’s an even bigger mistake that they do it in the first place, and the reason they do it in the first place is that our government has long been trying to project power around the world, not only militarily, but economically, backing up the efforts of Big Business, including Big Entertainment, our “pop culture” that is so anti-people. Many ideas are mixed; many think we ought to “spread democracy around the world” when we don’t really have it ourselves and long haven’t; this gets mixed in with our cultural hegemony; you have no idea how dismayed I am that I moved halfway around the world in part to escape Spider-Man underwear, only to find that it has followed me here and my son is now eagerly following the inferior, bad, and even poisonous ideas mixed into these “Marvel/DC universes”, etc. And that is among the more innocent things that we export in flooding the world with our cr*p. As a result, we get people who see that it is cr*p to resent it, and then us, and our military winds up getting used not only to impose policies intended to control the flow of oil and arms, but also these international markets and trade. And so American politicians, who are as corrupt as any you will find in Russia, work in orchestration with a media owned by the same paymasters to arrange war after overseas war (aka “The Forever Wars”, with all respect to Joe Haldemann). 9/11 began long before 2001, and wasn’t just because some Arabs “hated us” for no reason. A long train of interference in our name, both of attempts to manipulate and control, and betrayals, led to it and the very idea that “we” should be bombing Afghanistan.
From where I sit, we had TREMENDOUS capital of goodwill from what our grandfathers’ generation did in WW2, both in liberating Europe and Asia from the Axis Powers, and in helping Europe in particular get on its feet again. Everywhere I went as a young man across Europe, just before and after the fall of the USSR, I felt welcome as an American, and by 2000, I saw that welcome gradually begin to dissipate, as unilateral policies in our name sought to dominate the politics of other peoples.
So I think the idea of mistakes extends far beyond our understandings of the lands we seek to militarily dominate.
