Reality check:
According to that logic, Canada should already have that attitude to the US, since most of their population is inside aircraft range...
Huh, why the minus votes? Is there anything wrong with the argument or is this political believers' reactions?
Airplanes [edit: and rocket artilleri, for that matter] in range is functionally the same thing as such a strike capacity, but cheaper.
There is no reaction from Canada and won't be; see the democratic peace theory.
I believe prompt global strike (and similar schemes) to be highly unstabalizing and to be avoided at all costs. The global suspicion (with a country with 2000k+ nukes none the less) would be suffocating. If the USA employed such a system, the moment you acted as anything less than a white knight, the world be up in arms. And justly. Your friends (the UK and Canada and Australia) would start edging away. And then you're truly fucked. (Canadian).
