Clinton and Obama pulled 'bait and switch' on Netanyahu?

Just a couple of hours ago, I reported that a letter of assurances regarding the 'settlement freeze' extension was ready. It may not have been everything Israel wanted, but at least it was something.Now, there's a different report, which claims that there is no letter of assurances, and that President Obama and Secretary of State Clinton have pulled a bait and switch on Prime Minister Netanyahu.
