Under the moratorium, our laboratories have maintained our arsenal through the Stockpile Stewardship Program without underground nuclear testing, using techniques that are as successful as they are cutting edge.
Since 1992, in the place of testing, the United States has relied for "stockpile stewardship" on a host of computer-modeling, other simulation techniques and non-nuclear explosive tests that have provided insights into the performance of an aging arsenal.
Conflict resolution didn't exist as a field when Dr. Spock reigned, but a generation of scholars has introduced new techniques to resolve showdowns, from nuclear-arms pacts to general strikes.
