If John Bolton has agreed that Irans soon to be nuclear news today is serious,Why is the WH playing it down?

John Bolton is non partisan and has all the experience to evaluate todays news about the serious implications of 20% enrichment levels. He said that he recommends strategic limited strikes to set them back. He said that this administration is holding Israel back from doing what needs to be done. John Bolton said that Sanctions are completely useless at this point. It has advanced too far and they will be using the material in production of Nuclear weapons very soon.
