Tata has never had a civilian job in national security. (Since retiring from the Army, he has, in addition to his gig on Fox News, been a school administrator and the transportation secretary for North Carolina.)
His military career ended prematurely upon forging court documents and charges of adultery against U.S. military code.
While in the Army, Tata never held any position that involved policy, strategy, or long-term planning, and his highest responsibilities were on the operation level.
By the requirements of the position and by the standards of his predecessors, Tata is simply unfit for the job.
His apparent chief qualification? He has been a bombastic, pander-to-the-base commentator on Fox News. That’s a good enough criterion in the Trump administration.
