This post is primarily about the Iran nuke agreement and whether or not it is credible from a scientific standpoint, something these gentlemen are well qualified to discuss. In their judgment, it IS a decent agreement and they outline why some of the criticism is off-base (ok, just wrong). The politics of the issue should hinge on the substance of it, and whether or not it's workable. I trust you will take some time to read what they have to say.
I've already read what genuinely credible experts have written on the subject and so why would I read what a bunch of scientists gathered up by the Obama administration have written FOR the Dem Party on the subject?
