Are you kidding? They say it all the time. Your average Palestinian doesn't want war any more than your average Israeli. This is a product of the governments with the support of the religious leaders. Hell, the Palestinians have been more oppressed by Hamas than they have by Israel. Hamas does not represent them in any real way.
Then it should be easy peasey for you to post up a link to one saying it. Any member of Hamass saying it will do.
