I had a good long talk with him in Iraq.
My impression of him was that he had a well-grounded personality - a real mensch. Took his job seriously, but was not hung up on himself, and treated others well. Also, I was struck that he seemed very intellectually honest about the topic that he was studying - open to any ideas to solve the challenge at hand, and objective in assessing them.
Excellent points for recommendation.
A mind uncluttered with preconceived bias is one that will seek real solutions. Humilty.
Thanks for your insights.
