Just a few facts.
The decision to move the embassy was indeed taken, with very good reason, by the administration of George W Bush. The lease, which will last until 2953, was subsequently sold to the Qataris for £315 Million. This is a lot less than the £500 Million that it was valued at by property experts. The "negotiations" and resulting contract was drawn up by Obama's administration. I wonder if he would have sold it to the Israelis at such a knock down price. Obama insisted that the move would not cost the Americans a penny because the sale of this lease and other buildings would cover the £750 Million costs of the new Embassy which in fact turned out to be £900 Million.
