Tillerson is something Trump is not and will never be: a very successful American businessman. A realio, trulio, alpha male. Trump is a bully boy with an inferiority complex as big as all outdoors. Really successful alpha males have no time or patience for dilettantes such as Trump. I'm surprised Tillerson has lasted this long and apparently it's only because he's been talked out of quitting. I seriously doubt he will continue to allow Trump to undercut him at every turn and talk down to him via Twitter. If Tillerson last till the end of the year, which I understand was his plan, I will be very surprised.
