The bloggers at Powerline most of the time are way off for my taste, but occasionally one of them, usually Paul Mirengoff, comes through with a post I can applaud, even if I don't agree with every detail.
He's done it again,
this time working out the logic of the Iran deal. As I understand, he reluctantly concludes that it doesn't make sense to withdraw because we can't must the united stand on sanctions needed to reopen negotiations and if we don't withdraw, how does it make sense to decertify, as Trump is expected to do.
