Can someone direct me to a list of Jeffrey Sachs' foreign policy credentials?
Unless I'm mistaken, he's an economist--hardly an expert in international relations.
But, to hear him spouting off on MSNBC this morning, anyone could have been confused.
His self-righteous critique of the "catastrophic" foreign policy of this administration, and his smug calling-out of both Pres. Obama and Sec. Clinton about their Mid-East policy, was loathsome and obnoxious.
His "concern trolling" was SO obvious--especially when he pointedly reminded everyone that he's never been with "her", but with the "other".
= new reply since forum marked as read
is that he was the political "mastermind" behind Bernie's trip to the Vatican! 
That said, he has been an economic adviser to several foreign governments and to the UN and related organizations, particularly wrt sustainable development and very involved with the UN's Millennium Development Goals (MDGs).
His actual experience, however, has been as an academic. I do not believe that he has ever been "on the ground" in any meaningful capacity. He is, however, a proponent of the "Big Idea," a very idealistic view of how poverty can be overcome with few of the practical aspects that must be involved.
Here is an article from someone who has actually been "on the ground" that makes some good points: https://newrepublic.com/article/120178/problem-international-development-and-plan-fix-it
Mainly this:
What I want to talk shit on is the paradigm of the Big Idea—that once we identify the correct one, we can simply unfurl it on the entire developing world like a picnic blanket.
And he is a self-satisfied, mug little twit! 
Some heart and compassion, some of the right ideas, but absolutely arrogant and sure that HE is always right about absolutely everything.
Great minds!! 
To hear Sach's self-important broadside, you'd think that Obama willfully misjudged the necessity to take Assad out militarily when that "red line" was crossed.
So now, he's an "interventionist" because Obama wasn't. 
This morning, 30 seconds into Mika I had to change the channel in disgust, oozing her contempt for Hillary. No pretense of journalistic neutrality there!
And Joe had the morning off.
