The People's Republic of China is highly vulnerable to a missile attack. The Russian Federation is highly vulnerable to a missile attack. The Islamic Republic of Iran is highly vulnerable to a missile attack. For all the lack of coverage and cost of the American missile shield, these countries have no defense system against ballistic or cruise missiles. A nuclear war with Russia or China would probably spell the end of both sides and set back mankind technologically and economically, possibly irreparably. The only national leader who would seriously contemplate a missile attack against the United States, even a conventional one, is one who doesn't care about his own life.
