I think the best way of undermining radical groups is to undermine their powerbase, which is derived from psychology and the dependence of the Palestinian people. Hamas and other groups exploit the “us vs them” tendency that is natural in ALL humans to paint the current situation as a war against outsiders who are here to harm them. At the same time, they provide a number of critical services to the Palestinian people, which they can’t get elsewhere. To remove both of these in one fell swoop, we just need to have the US government start providing aid directly to the Palestinian people. Instead of spending $1mil on making Fatah media savy, drop $1mil worth of rice/beans and drinking water all over Palestine with big “Made in the US” logos everywhere, and pamphlets describing how the US stands with the Palestinian people. If the people get the food, they (or at least some of their children) can’t help but feel a bit grateful to the people that fed them, and if Hamas or other groups prevent the supplies from reaching the people, well then you have just created a situation where ‘us’ is the palestian people, and ‘them’ is hamas, which works directly against their power base. Put a handful of smart psychologists and sociologists in control of the timing of these drops, and I bet you could have a weaker Hamas within a year.

Unfortunately, neither side will risk losing face by voluntarily agreeing to this paln. It has to be rammed down both their throats by either the US or UN or some combination thereof. Meanwhile, many more will die so politicians can look brave and macho.
