Mustafa Barghouti, who is Secretary General of the Palestinian National Initiative, and was recently elected to the Palestinian parliament as an independent, is in Madison at the Havens Center. His first talk (yesterday) is already on the web (audio); my guess is that today’s talk will be up within 24 hours.
Havens Center talks are now routinely recorded and made available on the web, so you might be interested to check out the list here. Two that I would particularly recommend are our own Chris Bertram, and also Richard Miller, both on global justice issues.
