According to Donald Trump, Barack Obama founded ISIS, with the support of Hillary Clinton. According to Julian Assange of Wikileaks, Hillary clinton supplied weapons and ammunitions to ISIS. According to Michel Chossudovsky of Centre for Research on Globalization, Mossad had trained ISIS leader, Abu Bakr al-Baghdadi; while CIA supplied weaponry and weapons training to ISIS troops.
Conspiracy theorists in the Arab world have claim that the U.S.A. is secretly behind the existence and emboldening of ISIL, as part of an attempt to further destabilize the Middle East. After such rumors became widespread, the U.S. embassy in Lebanon issued an official statement denying the allegations, calling them a complete fabrication. NSA documents leaked by Edward Snowden revealed, the Iranian intelligence claim that ISIL leader al-Baghdadi is an Israeli Mossad agent and actor called Simon Elliot. Connections have been made with a map for "Greater Israel".
According to The New York Times, many in the Middle East believe that an alliance of the United States, Israel, and Saudi Arabia is directly responsible for the creation of ISIL. Egyptian, Tunisian, Palestinian, Jordanian and Lebanese news organisations have reported on the conspiracy theory.
