That the Commander of U.S. European Command (CINCEUR), Gen. Lyman Lemnitzer, was a critic of the Jupiter removals may have informed a Joint Chiefs of Staff decision to send him a background paper explaining U.S. decisions that could also be used for discussions within NATO. The backgrounder provided information comparing the reliability, vulnerability, and survivability, among other features, of the Jupiter and Polaris missiles. While the withdrawal of Thor and Jupiter missiles reduced Western “nuclear potential,” those reductions would be offset by an increase from 350 to about 800 U.S. strategic ballistic missiles, “some of which will be assigned to NATO targets.” Further, it “may be assumed that there will be no reduction in the present expectation of timely damage to the ACE [Allied Command Europe] targets presently covered by the Jupiters.”
