He ain’t even close to being up to the job.
No incoming president has been or will be... That is why they have security advisers, military, experienced diplomats in their cabinets and as advisors, as well as Senators and Congressmen that all discuss the issues. It is sophish to expect an incoming administration to have all the answers immediately, especially when the current Admin is doing their best to be obstructionist to the new Admin.
This will be an interesting transition, and very telling to the American public and the world.
