same as how Iran could be without US backed coup. All superpowers are bad for this world. But still, the world is still suffering from the mess last empire made.

I don't know what to think for Afghanistan, a government without ability to maintain stability is not useful, and Taliban is a bit backward, and I don't know if we can expect them to change when they take full control of the country. With modern weapons, something like a revolution would be impossible to happen in any country, AND a government not through revolution really does not last.
