It is no longer a question about "US or Iran," there are too many countries who today have nuclear weapons capabilities, including "crazy" countries in our books. . . like Pakistan and North Korea.
And, nuclear power is extremely important as a future source of energy for EVERY country. . .NO COUNTRY should be able to interfer with another country's right to develop nuclear energy. . which, unfortunately, is only a small step to nuclear weapons.
I totally believe that it is not a nuclear device that will destroy OUR culture.. .it is our self-destruction through greed and lack of economic progress and infrastructure progress. Just as it is not weaponry and military might that fell the Berlin wall, but the economic appeal of the rest of Europe in particular, and it is not military might who has moved China away from stage 1 or 2 Communism, but it is ECONOMICS. . .it is the appeal of a healthy economy for a majority of people who will create revolutions from the inside.
We spent Trillions in getting rid of Sadam Hussein. . .we could have saved all that, and saved our economy by letting the people of Iraq lead their revolution, just as Tunisia, Egypt, Libya, and now Syria are doing.
