Mark Malloch-Brown has been involved in international affairs for more than three decades. The former journalist turned economist served as vice president of the World Bank, before being named Deputy Secretary General and U.N. Chief of Staff under Kofi Annan. In that position, he drew controversy for his outspoken criticism of the Bush Administration’s Iraq policy and what he called its "UN-bashing." Now out of public and political office, Malloch-Brown has written a book, "The Unfinished Global Revolution: The Pursuit of a New International Politics."  Millions of demonstrators filled the streets of Cairo and other cities around the Arab world recently, voicing their opposition to the old order, corruption, inequality and the lack of freedom. As a former UN official who helped draft the first "Arab Human Development Report" a decade ago, Mark Malloch-Brown says the tidal wave is long overdue.
