Thanks to a "lurker" a recommendation for a new book 'Yemen in Crisis: Neo-Liberalism and Disintegration of the State' by a SME, Helen Lackner, and a short comment:
Lackner combines elegant writing with incisive and lucid analysis … This is an indispensable guide to understanding
Yemen’s profound and tragic problems.
