   He never should have been jailed and it's embarrassing that John Kerry and Obama negotiate with Iran as innocent Americans remained locked-up in prison, president Obama is a complete fool for trusting a country that's been lying, cheating, murdering and sponsoring terrorism around the globe for 37 years. Empowering Iran with sanctions relief is like Neville Chamberlain writing a $150 billion check to Adolf Hitler hoping he'll play nice and behave. This Iran deal is an insane disaster and this White House has lost its mind.

   If you have spent any time watching Boko Haram, you would know that Shekau is truly insane and his version of Islam is even too radical for Islamic State, a mixture of part witch doctor/part voodoo/part radical Islam. He is usually screaming, surrounded by a posse, and at least one tank, this last video is a totally new Shekau, calm, cool collective.Someone is directing his image. My thought is he is a wild card that Islamic State cannot afford to ally with unless they rebrand him or get rid of him entirely.
