I don't like it - but I do agree with you that that is the way it is.
However, I thought one of the underlying currents of the Bill of Rights is that, at least in theory, they were rights afforded all of man. Therefore, expanding out on that - everyone in the world should be able to have nukes.
In the concrete, the U.S. Constitution only directly protects the rights of its citizens and through some fairly recent activist judges, residents of this country, both legal and illegal.
It doesn't necessarily protect the rights of citizens of other countries, and certainly doesn't protect the rights of the governments of other countries, if governments can be said to have any rights at all.
But I'll bite. Let's say that the 2nd does protect the rights of every person on earth to have nukes. The Constitution also guarantees a republic form of government.
Let's start overthrowing any government which it's a republican government, ok?
