Not exactly. The whole idea was predicated on the obsolescence of nuclear weapons in modern conflicts, so in a sense it was partially predicated on improving non-nuclear defensive capabilities. His suggested "pitch" to countries to get them started was the massive cost of maintaining weapons that are not intended to actually be used- they just sit around and act menacing. He posited that this was a pretty juicy incentive and if you could conceive a scheme where countries could all disarm simultaneously while maintaining a balance of power (and thus the disincentive against the use of weapons) that it might actually work. This is obvious of course and pretty standard thought. His real focus was on the importance of ways for the weapons states to mutually verify the disarmament of the other states in a technically rigorous manner but all of it was interesting.
