The Left Forum starts this week (May 20-22). This year it's in New York City and my friend The Talking Dog will be participating in a panel on Guantanamo on Saturday May 21st at noon: Close Guantanamo Now or Move Guantanamo North?
War Criminals Watch has more on that and other panels of interest.
If you have never gone to the Left Forum and you are in the NYC area (or can get there) this is a must event. Past conferences have included talks by: Noam Chomsky, Arundhati Roy, Angela Davis, Harry Belafonte, Naomi Klein, Michael Moore, Cornel West, Bolivian Vice President Álvaro García Linera, Amy Goodman, Slavoj Zizek, Grace Lee Boggs, RoseAnn DeMoro, Marina Sitrin, Nnimmo Bassey, Immortal Technique and Oliver Stone.
