I don't know enough about the situation to say for sure that Iran is or isn't a threat, but what I do know is that our military leaders and media have lost all credibility when it comes to reporting on such matters. I also know that Iran's uranium enrichment plan is so painfully slow that it has taken them many years to get where they are, and they are still quite short of a nuclear weapon. So, I do not buy into the urgency of this matter.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
