For some years USA has been building hundreds of huge underground bunkers - underground cities deep in the mountains all over the country. These underground cities are well equipped with modern facilities and amenities like roads, rails, electric power, reservoirs, hospitals and schools. USA may launch a surprise nuclear attack on Russia and China any time soon. These extremely mad American leaders think they will be safe in these underground cities . They have no qualms about how a nuclear exchange with Russia and China can kill hundreds of millions of people world wide including ordinary Americans so long as they stupidly feel they are safe in their underground cities.America is nurtured on wars - perennial wars . The country is now run by extremely crazy and very mad people. They believe America should always be on top and no other country or countries would be allowed to come close to America's top position in military power, finance , wealth and riches in status. In view of this they feel compelled to take down Russia and China, the only two countries obstructing its path to complete world domination.
