While some people on the left side of the aisle believe they can live with a nuclear armed Iran, this piece "A nuclear-armed Iran would not be good" reminds us that it is not okay to tolerate a nuke-armed theocratic regime in the region:
"There is no doubt the US has given the deepest possible consideration to taking military action against Iran's nuclear plants. When I interviewed US Vice-President Dick Cheney earlier this year, he endorsed Republican senator John McCain's formulation that the only thing worse than a military confrontation with Iran would be a nuclear-armed Iran."
"A strike on Iran would be an awesomely dangerous and fraught action to take. Allowing Iran to develop nuclear weapons may be equally as dangerous. There are no good options."
