Abbas' support for terror

Reading a little between the lines of the news the past couple of days....

Mahmoud Abbas outlawed the Hamas militia (the "Executive Force") that have been fighting his Fatah-backed militias.

Fatah's Al Aqsa Martyr's Brigades terrorist group hold a massive rally supporting Abbas and "national unity."

Al Aqsa, of course, is responsible for countless terror attacks againstIsrael, both bombings and rockets.

Abbas never outlawed Al Aqsa, even though he at the very least has more influence over them at at most he is their leader. They can walk the streets of Palestan with their ski masks and RPGs without any fear from the "security forces." They can also fire rockets without fear that Abbas will stop them (Hamas has taken no credit for the past month's rocket attacks; they've all been Al Aqsa and/or Islamic Jihad.)

Is there any other possible conclusion than to say that Abbas supports terror?
