Leopard,If Russia where to try to shoot nuclear weapons at us 80 to 90% would be intercepted by the U.S. and the U. S. nuclear bomb would head to Russia . The Russians do not have the means to intercept our nuclear bombs, so this is why that would not happen. Putin know this would not work. This is why I know that if Putin wants to destroy the U. S. it will have to be an EMP. No other way.
