I wouldn’t call accelerationism a serious theory. Most of the people who talk about it wield zero power, and the decisions by people in power here seem to be well-explained by some flavor of personal or material interests, not some desire to accelerate anything.

If anything Iran’s playbook seems the opposite of accelerationist: carefully let the US strangle itself and withstand its death throes. Think of how many times people wanted them to lob everything they have straight at Israel all at once.

If US leftists were magically given a button that said “accelerate” we should probably refrain from pushing it until we’ve cultivated enough organization to actually seize and hold power, rather than whatever paramilitary. Plus since the US has nukes it’s kind of better for the world that it dies gradually, to some degree.
