Obama threatened retaliation against Israeli action on Iran if Israel didn't release 'Palestinians'?

In an earlier post, I discussed (and cast doubt on) the claim that Israel traded 104 terrorist murderers for an American attack on Iran. But what if what happened was that Obama and Kerry told Netanyahu that if we didn't release the 104 terrorist murderers, and return to the table with the 'Palestinians,' when and if Israel bombed Iran, the US would leave us to face the consequences alone?
