A better Iran deal for Obama/Kerry would have been a fantasy like a Superbowl title for the 1976 Tampa Bay Buccaneers (0-14), a World Series title for the 1962 New York Mets (40-120), or an NBA championship for the 2012 Charlotte Bobcats (7-59), and for the same reason. The players on a team matter, and Tampa Bay could not have done worse even if they were trying to throw the games.
As for Obama, I assume he is trying to throw the game, and his record supports that conclusion. A better deal could not have been obtained because he was trying for the worst deal that Congress and the media would tolerate - and succeeded.
I suspect hussein is gritting his teeth from realizing that he could have gotten a deal that transfers “safe” nuclear warheads and delivery technology straight from American arsenals to Iran past this Congress.
