Monday Papers (or the al-Huthi conflict)
Gregory Johnsen, a former Fulbright Fellow in Yemen, is currently a Ph.D. candidate in Near Eastern Studies at Princeton University. Johnsen has written for a variety of publications on Yemen including, among others, Foreign Policy, The American Interest, The Independent, The Boston Globe, and The National. He is the co-founder of Waq al-Waq: Islam and Insurgency in Yemen Blog. In 2009, he was a member of the USAID's conflict assessment team for Yemen.
Muhammad al-Qadhi has this article in the National, which discusses the latest clashes between al-Huthi supporters and the potential for a sixth round of all out war between the two sides.
A couple of notes on the article. First, I'm not sure how accurate the 23 percent number is. I don't think anyone has firm numbers on Yemen, which is often why one sees so much guesswork. Also, I would be wary of identifying Salih as a Zaydi, traditionally he is, but this is not where he gets his legitimacy or authority from - he has other identities that he capitalizes on. Also, I would be wary of reducing the al-Huthi conflict to a simple: they want to restore the Imamate, at least the Imamate as it was articulated by the Hamid al-Din dynasty.
In another worrying sign, the Yemeni government has started court proceedings against 12 individuals alleged to be al-Huthi supporters. If the government wasn't setting the table for more fighting it would be more apt to pardon or not bring charges - add this to the list of indicators.
