Maybe, but the Afghans were pleasantly surprised at the detail of the calls they had, and the questions, and follow-up questions they received from Trump. Somebody did the President a great disservice by telling the Afghans that, and they should be corrected.
This is no longer The Era of Obama; this is the era of Trump, and responses to such slights of The President ought to reflect that. Trump's not the sort to re-educate people who already know better; he hasn't got time for that crap. Whomever it is knows their job, has a basic knowledge of Trump's style, but intentionally communicated an erroneous picture of Trump's expectations.
They don't need re-training; they need replacing.
