By neglecting — and in some cases even opposing — essential modernization programs, arms-control proponents are actually undermining the prospect for further reductions of the U.S. nuclear arsenal. As our nuclear weapons stockpile ages and concern about its reliability increases, we will have to compensate by retaining more nuclear weapons than would otherwise be the case. This reality will necessarily influence future arms-control negotiations, beginning with the upcoming Strategic Arms Reduction Treaty follow-on.
