Re:America's nuclear arsenal to cost $946B over next decade by pfdietz on Sunday April 27, 2025 @10:19AM (#43812129)
The goal of the US nuclear unbrella isn't just to defend the western world, it's to inhibit the rest of the western world from building nuclear weapons.

At some point there may be a phase change where the US abandons this goal. In that world, the rational strategy becomes one of strategic disengagement, so that if nuclear war breaks out (or a conventional war that risks going nuclear) the US is not drawn in. The lesson becomes that of WW1, not WW2.

"The goal of the US nuclear unbrella..."

So say you. This is a discussion about costs, as opposed "goals." Were I to stipulate the claim you make, then it's all be a terrible failure: at least three US allies have built and currently operate a nuclear arsenal.
