This sentiment was echoed by Digby a few days back, when she wrote:
Am I the only one who finds it just a little bit odd that the American officials loudly claiming Iran cannot be trusted to fulfill any deal are simultaneously pledging that they will not fulfill any deal? Is it possible they have such little self-awareness?
I'm sure the Iranians will have to be very closely watched. There's a reason why this agreement is necessary in the first place. But bellowing about how untrustworthy they are while boldly asserting your own untrustworthiness doesn't exactly set a good example.
Which again brings to mind the immortal words of Duncan Black, who blogs at Eschaton, entitled Wars are Bad:
And if for some reason the people who run the United States feel the need to start one, it means they've failed. It means they should all resign in shame and let someone else clean up their mess. This country has immense power - military, economic, political - and if you can't use the latter two, along with the implicit threat of the first one, to make war unnecessary then you've fucked up and it's time to go home.
