"... so it would be pointless to have a long call. However, we were pleasantly surprised at how much time President Trump spent asking very informed questions. The first time the presidents spoke, the questions Trump asked impressed us. 'How can you win in this fight [against terrorism]?' he asked. 'What do you need to become financially independent?' and 'How can American business invest in Afghanistan? How can we develop businesses and mining in your country?' Trump would listen intently after each question, often asking follow-ups. Trump's second call with our president was even longer than the first. Asking these types of questions for our country is something the Obama administration never did. The Obama administration was the most academic administration we have ever had to deal with but the Trump administration has been the most thoughtful and intelligent."
From "I Had Dinner With the Afghan Ambassador. What He Said About the Differences Between Trump, Obama Is Stunning" in Independent Business Review.
ADDED: Interesting to think about the contrast between "academic" and "thoughtful and intelligent." The ambassador seems to set them up almost as opposites.
