Does the Bush administration have the right to stage a bloodbath in the Gaza?

Led by Gen. Keith Dayton,five U.S-trained and financed Fatah brigades are now poised to invade Gaza to destroy the legally elected government of the Palestinian Territories; as we know Bush & Co. simply rejected the election results in 2006. The good general wishes to install as the fascist dictator of Gaza the deeply corrupt and brutal Mohammed Dahlan, a man as unpopular in Gaza as he is popular in tel Aviv and Washington; he is a protege of Elliot Abrams and a stooge of the Tel Aviv regime. Should this Bay of Pigs type operation be countenanced by other governments?
