Trump is clearly looking for a Chief Negotiator rather than a Chief Bureaucrat.
The problem is Trump isn’t negotiating an oil deal here. Even considering Putin’s BFF for Sec. of State will have real world consequences. If Trump is not careful we will get into the situation we have with the kenyan where nobody trusts the United States. That’s not how to advance his agenda and is certainly not good for business.
Negotiating skills are transferrable from industry to industry and from industry to government. He has a working relationship with Putin, your characterization of “BFF” is inaccurate.
