With the recent scare in Hawaii, we naturally consider the need for protection, and this has everything to do with perception of the probable risk.
When it comes to “the doctrine” of nuclear deterrence, we discover that it’s a free market, after all.
If we waste the world by accident, which is the defining characteristic of an act of the gods (a twist of fate beyond our control, by force of a random existence), then we know the imperative value from which the need for protection derives.
The thermal-nuclear scenario is an exercise in existential logics. It is expressed here in the plural because, due to the unknowns that define the fickle fate of a probable existence, the future is multiversal. Like Kant said, however, pondering the moral imperative of a natural existence, we know what the imperative is despite not knowing if or when fate twists its way to “just happening” now.
(As in the abstract image above, you know freezing rain to snow is possible, so you need protection. Since you do not know when, there is an alert system when it probably will happen. Meteorologists express its occurrence with cyan and magenta colors, and when you see those colors you come closer to knowing if it will take the shape of actually happening to you. The imperative impression is to be protected since the risk is likely to happen, but maybe not to you now.)
The alert may have been false, but paradise is lost, nevertheless, yielding to the protection, which is, by all accounts, imperative.
