It doesn't matter which organization or individual is doing the actual shooting. Hamas is the leading entity in Gaza and thus stop the attacks or at least show that they are doing EVERY possible action to stop it including call for international help if they cannot do it by themselves.
I haven't seen this happening at all. Not even slightly.
What is Abbas doing? He is the head of Fatah, and Al Aqsa claims they are firing the rockets. Can't he control his own military wing?
Two weeks ago Hamas was allegedly summarily executing Fatah members for collaborating with the Israelis. These guys are not friends. Israel just destroyed the Gaza government infrastructure. Any Hamas leader who shows his face in public does so with an Israeli target on his head. They destroyed the main prison. A month ago you had a reasonable argument. Hamas was in charge, and though limited in their capabilities by the Israeli blockade were clearly not making enough of an effort to stop rocket fire.
Now the Hamas government is in disarray. Your criticism is like criticizing the New Orleans police force for not doing enough to stop looting after Katrina. Except the disaster this time was not an act of God.
Well, Olmert has played his last card and lost. Perhaps Netanyahu will have better luck. 1300 Palestinians and 13 Israelis is a steep price to try to win an election.
