Allahpundit has a story out of the memory hole about a United States apology to Iran in 2000 during the waning days of the last first black president. He suggests it might tone down any kind of blathering formal apology A'jad wants thrown into the 'conciliatory letter' the State Dept is currently drafting up to send to the Mullahs. We can hope.
Obama said 'no preconditions' and we know he's going to apologize, but is his boot lickin' street one way? How about asking Iran to simultaneously apologize for all the things they've done, including keeping members of bin Laden's family under 'house arrest', for example.
And perhaps Hillary Clinton could deliver the letter personally.
