CarolC: "So if even one nuclear armed missile gets through, NO lives will have been saved by this system.
On the other hand, if we do what is needed to make the world a less violent place, it simply won't be an issue"
It seems to me that it will still be an issue as long as there is at least one person who perceives that the US is in the wrong. And I fail to see any realistic view that would say that everyone will ever agree the US acts correctly, rergardless of US actions or policies- SOMEONE will always be upset.
