Obama sends a video to Iran offering "a new beginning." Iran responds by welcoming the video but demanding that the US recognize "past mistakes," end sanctions and end support for Israel.
First of all, the US will not end support for Israel, but it will support a Palestinian state, something the previous administration did not seek for most of its term. Second of all, the latter demands are something you can seek to get in the course of negotiations, not as a precondition.
sigh... the Iranian elections cannot come soon enough.
