There's nothing libertarian about this. Inventing and securing dangerous technology is an affront to individual freedoms. The idea of proliferation as deterance is totally separate from libertarianism and seeded more in fear than anything else.

The prioritization of individual freedoms above most other considerations (along with the assumption that it will work out better in the end) is what libertarianism is all about. Maybe you’re a libertarian without realizing it? :)
