Iran and North Korea

For a number of years I have felt that the policy that the United States of America should have towards the North Korea and Iran concerning the nuclear weapon is one of quick retaliation. There would be no need of trade sanctions or restrictions, constant warnings to quit their nuclear research for energy. The policy needs to be clear and direct. If any nuclear bombs hit Israel, there would be an immediate retaliation against one or both of those countries of a nuclear bomb on the at the location of government headquarters. I think that this would cause the countries to view there nuclear weapons program.
