Russian weapons testing

Regarding the Opinion page article "Yeltsin's Ominous Move to Resume Nuclear Testing," May 11: The first two-thirds of the article is devoted to possible reasons why Russia is taking the action it is and pointing out that it can scarcely afford such activities. Only in the last quarter of the article does the information appear that the US is planning another six tests in 1992 to ensure that our warheads still work. Doesn't this more than explain Russia's current concern and motivation? Malcolm Tweedy, Fort Davis, Texas
