Credentials and experience getting things done. Give me Blinken and Hillary and I'd send them over lickety-split and I bet you they'd have a deal done in hours.

The biggest thing is to follow norms. We must conform to what has always been tried. Great leaders conform. I read that once. Maybe it was here, or maybe it was there, but I read it, and, dammit, it made sense. Do not deviate from norms, be it foreign policy or dreadful SCOTUS decisions from the past. Conform.
