manual DNA-EM-1, updated 1981 (U.S. Freedom of Information Act). Under most atmospheric conditions no fallout effects would occur from the use of a neutron bomb, according to that manual, as the combination of 500-meter burst altitude and low yield prevents fallout in addition to significant thermal and blast effects. The reduction in damage outside the target area is a major advantage of such a weapon to deter massed tank invasions. An aggressor would thus be forced to disperse tanks, which would make them easier to destroy by simple hand-held anti-tank missile launchers. Cohen's backing of investigations into these controversial ideas won him some media attention after many years of being ignored. In 1992 he was featured in the award-winning BBC TV series Pandora's Box, episode "To the Brink of Eternity", discussing his battles with officialdom and colleagues at the RAND Corporation. Cohen controversially argued: "When we started this systems analysis business, we stepped through the looking glass where people did the weirdest things and (used) the most perverse kind of logic imaginable and yet claimed to have the most precise understanding of everything." Alleged support from the Pope for low-yield tactical nuclear bombs Cohen reportedly worked in France on low-yield, highly discriminate tactical nuclear weapons in 1979–80. He claimed that he was awarded a medal by Pope John Paul II in 1979 for his bid to reform modern warfare. Author Charles Platt reported in a 2005 profile of Sam Cohen that "... he showed me the Medal of Peace that he had received from the Pope in 1979." At the time, Warsaw Pact forces had a massive tank superiority in Europe (though NATO maintained an overall strategic superiority); the Christian Science Monitor reported in 1981 that there were "19,500 tanks in the Soviet-controlled forces of the Warsaw Pact aimed at Western Europe. Of these, 12,500 are Soviet tanks in Soviet units. NATO has 7,000 tanks on its side facing the 19,500." A deterrent which was designed to minimise civilian casualties was a step away from the risk of indiscriminate warfare. The neutron bomb's killing by neutron radiation is different from the fallout of a normal high yield thermonuclear weapon because it can be controlled more precisely, restricted to military targets and kept away from civilians. The speed of modern warfare meant that the civilian population would be unlikely to be able to withdraw from combat zones and would suffer a
