Then what are you claiming. Hamas is the govt. and totally in charge of Gaza and controls a huge army of terrorists, for which it receives armaments such as rockets, bombs, etc. and money from Muslim entities. None of the other terrorist groups in Gaza dare to breath without Hamas' permission.
Like I said, stop digging:
Hamas - Wikipedia, the free encyclopedia
Hamas (Arabic: حماس* Ḥamās, "enthusiasm", an acronym of حركة المقاومة الاسلامية Ḥarakat al-Muqāwamah al-ʾIslāmiyyah, "Islamic Resistance Movement") is the Palestinian Sunni Islamic or Islamist[5] organization, with an associated military wing, the Izz ad-Din al-Qassam Brigades,[6] located in the Palestinian territories.
The Izz ad-Din al-Qassam Brigades, Hamas's military wing formed in 1992, is named in commemoration of influential Palestinian nationalist Sheikh Izz ad-Din al-Qassam. Armed Hamas cells sometimes refer to themselves as "Students of Ayyash", "Students of the Engineer", or "Yahya Ayyash Units", to commemorate Yahya Ayyash, an early Hamas bomb-maker killed in 1996
The brigades have a substantial weapons inventory of light automatic weapons and grenades, improvised rockets, mortars, bombs, suicide belts and explosives. The group engages in military style training, including training which take place in Gaza itself on a range of weapons designed to inflict significant casualties on military targets.
While the number of members is known only to the Brigades leadership, in 2011 Israel estimated that the Brigades have a core of several hundred members who receive military style training, including training in Iran and Syria. Additionally, the brigades have an estimated 10,000 operatives "of varying degrees of skill and professionalism" who are members of the internal security forces, Hamas and their supporters. These operatives can be expected to reinforce the Brigades in an "emergency situation".
According to a statement by CIA director George Tenet in 2000, Hamas has pursued a capability to conduct attacks with toxic chemicals. There have been reports of Hamas operatives planning and preparing attacks incorporating chemicals. In one case, nails and bolts packed into explosives detonated by a Hamas suicide bomber in a December 2001 attack at the Ben-Yehuda street in Jerusalem were soaked in rat poison.
