You DO kind of have to accept it could have gone either way. When you have a regime that don't trust it's own people you can't be so sure they will suddenly roll over and play dead when they are isolated. Paranoid leaderships have before done pretty crazy things.
When cornered (as Iran are close to being as a result) there's a good chance it does end pretty. I think you're being rather narrow minded and on with the self righteous "we have a right to know" crap if you think otherwise.
