In addition, it's important to remember who's ruling Israel these days: Sharon-type Zionist maximalists who make the point of stomping on -- or thumbing their noses at -- the totally Palestinian Authority and Fatah whenever they get a chance. (Think about the gratuitous destruction of PA computers and the like when the IDF invaded Palestinian lands; think about the Wall.) You can imagine that many Palestinians thought about tit-for-tat. After all, who's toughest in their opposition to Israel, Fatah or Hamas? The Sharonicks and their less-secular Zionist maximalists have produced a mirror-image resistance.
BTW, the corruption of Fatah is partly a result of the "peace process." The US and Israel wanted a tame Arafat, so they bought him. The recent campaign help that the US provided to Fatah is in this tradition. -- Jim Devine
