I know almost nothing about Iran, nothing about what our current sanctions policy actually is, nothing about about what sanctions are being lifted in this current deal. I have read many articles on the subject over the past couple of days and have learned very little. I know we had "tough" sanctions (yay!) and apparently now we're going to have wimpier sanctions (boo!).
I doubt most of the people bloviating about Iran know any more than I do. Some of them, however, seem to think SMASH BAD GUY is only smart policy option ever.
