From Middle East and terrorism Blog, Wednesday, March 14, 2012, by Mordechai Kedar:
...The Gaza Strip is no different from the rest of the Arab world, so tribal culture is alive and kicking in the Gaza Strip too. Ever since the Hamas movement took control of Gaza trip in 2007, it has transformed itself from a gang of jihadists into a ruling organization which has a state, government, advisory council, legal system, police, military and economic bodies.
Thus, Hamas has turned into a standard Arab state, which is attempting to impose its agenda upon the tribes and the clans that live in the Strip. The State of Hamas serves the interests of the group that leads it, and therefore it is in constant conflict with the tribes and the clans and must reach agreements with them.
The minor movements - Islamic Jihad, the PRC (Popular Resistance Committees), the Salah-a-Din Division, the Army of the Nation, the Army of Islam and others - function like tribes, challenging the authority of the state, which is in the hands of Hamas. Today, these groups are doing to Hamas what Hamas did to the PLO twenty years ago when the PLO was in power. The widespread corruption among the top echelons of Hamas strengthen the influence of the small organizations that oppose Hamas.
...Hamas ...has not changed its covenant or its sole goal: to eliminate Israel and bring an end to the "occupation" of Jaffa and Acre, not only Hebron and Nablus. However, in the present historic phase it is suspending its battle against Israel in order to establish a state which, when the time comes, will be the basis from which the war of the destruction of Israel will be waged.
The small organizations do not accept this suspension of jihad and call Hamas derogatory names such as "The Israeli Border Guard" and the "South Lebanese Army".
From a practical point of view, Hamas is capable of eliminating the organizations, just as it dealt with the Army of Islam, of the Dughmush clan in August of 2008, and as it eliminated Sheikh Abd Al-Latif Moussa's Islamic Emirate of Jerusalem in cold blood in August of 2009 in a mosque in Rafah, murdering him, his wives and children and 24 followers. As of today, in the year 2012, Hamas refrains from imposing itself on the small organizations by force of arms so that it will not become the "Israeli Border Guard"in the eyes of Gazans, and prefers to come to an agreement with them; to compromise with them and to calm them down.
This is the reason that Hamas functioned during the last round of rockets as a moderating and calming force...because they have become a state, and the state must, in one way or another, impose its agenda on the bodies that consider it an illegitimate organization because it has suspended active jihad against Israel...
