|During the Cold War, The Soviet Union was in possession of over 30,000 nuclear weapons, including the world's most powerful nuke: The SS-N-18, codenamed "SATAN". It contains 10 MIRVs (Multiple Independant Reentry Vehicles), each with a 750kt warhead. One SS-18 could level Los Angeles, New York, Detroit, Boston, Washington DC, San Francisco, Seattle and numerous other cities. Consider the fact that dozens were built.. In a first-strike attack, the USSR could wipe out each and every American Minuteman silo and every major American city. If my info is correct, the USSR had enough strategic nukes to strike every city in North America 11 times. It is easy to see why the American presidents were terrified of this weapon and the "window of vulnerability" it created. Any thoughts or opinions? Just making a point.
