But to play along, NO, because 42 U.S. Code § 2122 makes that illegal. If nuclear weapons are ever issued as standard individual weapons to soldiers, then they will be covered by the 2A via the Militia Act. Until they are, nukes are not covered by the 2A.
The constitution and current laws, clearly define what you can or can't have under the 2A. NFA laws exist as were voted to control Automatic weapons, SBR's, Silencers, Sawed off Shotguns etc. Until new laws are enacted that change this, it's pretty clear.
I for one don't want new laws written to change my first amendment rights, lest we get to the point where the 2nd is needed to defend the first.
If it was to serve its original purpose, it arguably might need to (just as private ownership of the heaviest artillery was in the early Republic not unheard of) but any hope of it serving its original purpose has been lost since at least the late 19th Century with the expansion of paramilitary police forces, and the final nail in it's coffin was drilled with the transition to a fully professional military after Vietnam, and what weapons are covered doesn't really matter any more to it's intended function, only to the degree of incidental harm it inflicts while failing to protect from the harms of the isolated culture of large permanent military/paramilitart internal and external security forces.
May the citizens rip apart the federal LE agencies into a thousand pieces and scatter them into the wind.
That's a 10^1000 multiplier. It doesn't even matter what unit you use really...
