I wondered if the aims and objectives of the above have changed since May 2005, when the US Navy produced their report, part of which follows....
Islamic Resistance Movement
HAMAS was formed in late 1987 as an outgrowth of the Palestinian branch of the Muslim Brotherhood. Various HAMAS elements have used both violent and political means, including terrorism, to pursue the goal of establishing an Islamic Palestinian state in Israel. It is loosely structured, with some elements working clandestinely and others operating openly through mosques and social service institutions to recruit members, raise money, organize activities, and distribute propaganda. HAMAS’ strength is concentrated in the Gaza Strip and the West Bank.
HAMAS terrorists, especially those in the Izz al-Din al-Qassam Brigades, have conducted many attacks, including large-scale suicide bombings, against Israeli civilian and military targets. HAMAS maintained the pace of its operational activity in 2004, claiming numerous attacks against Israeli interests. HAMAS has not yet directly targeted US interests, although the group makes little or no effort to avoid targets frequented by foreigners. HAMAS continues to confine its attacks to Israelis inside Israel and the occupied territories.
H'm. Yassir Arafat is turning in his grave.
