from The Wall Street Journal by DAVID LEWIS SCHAEFER
Once a country passes a minimal threshold, there is no reason to suppose that increasing its nuclear arsenal heightens the likelihood of its use. The only means of deterring rogue states from using (or more likely, threatening to use) nuclear weapons once they have acquired them are first, the capacity to threaten a much more massive response, and second, an effective program of missile defense.
Reducing our nuclear arsenal only gives outlaw states (including China) the incentive to increase theirs, to try to rival ours. And eliminating nuclear-weapons testing reduces the reliability of our arms and hence their effectiveness as a deterrent.
