Soon after their disclosure, MJ-12 was absorbed into many other alleged conspiracies; William Milton Cooper's works are key in this intoducing MJ-12 to a wider, conspiratorialy-minded audience. Some of these later versions insist that the "M" in "MJ-12" stands not for "Majestic" but for "Majority". Many theories suggest that MJ-12's efforts continue to the present.
According to the testimony of Dan Burisch, Majestic-12 are today in fact working for the Committee of the Majority, a Masonic organisation which is coordinating alien contact with earth, as well as the operations towards a New World Order. Under this direction, MJ-12 are responsible for all scientific operations at Area 51, Dulce, New Mexico, and the Frenchman's Mountain installations. This is but one conspiracy theory suggesting that MJ-12 have far-reaching powers (not unlike the Illuminati), and are aiming for one-world government.
According to less extravagant conspiracy theory lore, Majestic 12 was created with a more humble goal: to cover up alien activities on Earth, and liaise with the aliens to obtain technology in exchange for knowledge and testing on human biology.
