During the 1990s, the Hamas infrastructure within the United States was complete. It consisted of a propagation outlet, the Islamic Association for Palestine (IAP); a financing wing, the Holy Land Foundation for Relief and Development (HLF); a command center, the United Association for Studies and Research (UASR); and a defense mechanism, the Council on American-Islamic Relations (CAIR). Today, only the latter exists, along with a remnant of the IAP, the Mosque Foundation. Both have a presence in the Chicago area, where group and mosque are working hard to indoctrinate young Muslims into radical Islam.
In 1981, two Muslim Brotherhood entities, which later would be widely regarded as being aligned with the terrorist Hamas, were established within the Chicago area of Illinois. One, the IAP, was created as a collaboratory effort between future Hamas leader Mousa Abu Marzook and future Palestinian Islamic Jihad leader Sami Al-Arian. Soon after the onset of the violent Palestinian Intifada against Israel, which began in 1987 and which gave birth to Hamas, the IAP became a publishing house for the Hamas charter and Hamas terror training videos.
