'all negotiations are a waste' Well if they said that they would probably be right. After all they observed numerous ceasefires in the past only for Israel to unilaterally end them. 2000-2008: "79% of all conflict pauses were interrupted when Israel killed a Palestinian, while only 8% were interrupted by Palestinian attacks (the remaining 13% were interrupted by both sides on the same day)" http://www.ifamericansknew.org/cur_sit/reigniting.html They offered a longer term ceasefire days before Cast Lead in return for a lifting of the siege. Israel said 'no thanks'. So yes negotiations are a waste of time until Uncle Sam takes a stronger line with their errant attack dog.
