In our nation's entire history, there has never been an administration with less credibility than Barack Obama's. For this administration, the truth seems little more than an unfortunate inconvenience to communicating its utterly incoherent message.
Witness the "agreement" with Iran to curtail its criminal nuclear proliferation. I hope Secretary of State John Kerry at least made the failed Persian state pinkie swear, and that the citizens of Tel Aviv have stocked up on really good sunscreen.
How can you tell when a rogue state or the Obama administration is lying? Their lips are moving.
