As for ESTJ = Te Si Ne Fi, his feelings are all about others, no Si (as mentioned), his intuition is internal and poor, he doesn't show Te. It's Ti and it doesn't show to us.
I'm guessing at this. As an INTP = Ti Ne Si Fe myself, I'm going on the Ne and Fe I see.
Today he popped in at the United Nations and let us know China deserves criticism. This in the middle of trying trade talks. He's right up front with that. Call it Se with Ti behind it. Do you agree or maybe disagree?
