I suspect part of the transition to this may require a doctrinal shift around force posture that pivots more toward allowing allies to unilaterally impose cost rather than the US becoming entangled in a strategy of denial. I am thinking about the weapons that align with this transition at the nation state level, which then will lead to trickle down decentralization over time.

I suspect it may be impossible for it to be grassrooted bottom up with communes: El Salvador, Prospera, Solano, etc, which of course are not taken seriously in their own right, for cities will not effectively defy states, nor are they currently able to defend their territory against a centralized hegemon, so no one will truly defect even if they signal conditional interest.

It will likely be many decades of international decoupling at the conventional layer, with a shift toward cost imposition as a stable deterrent, which will help the world realize the strategy of denial against tyranny fails in securing liberty.
