How ISIS Was Really Founded

Overview

  • 2006: Rebranded as the Islamic State in Iraq (ISI) following al-Zarqawi's death.
  • 2013: Returned to Iraq as a powerful force, later known as ISIS.

Key Events and Timeline

Al Qaeda in Iraq (AQI)

  • 2004 Formation: Created by Abu Musab al-Zarqawi, a Jordanian Islamist.
  • Insurgency Role: Major player against US-led forces and the new Shiite government post-Saddam Hussein.
  • Sunni Recruitment: Appealed to Sunni minority’s grievances against Shiite dominance.

Rebranding and Defeat

  • 2006: Abu Ayyub al-Masri took over post-Zarqawi's death, declaring the Islamic State in Iraq.
  • 2008: Largely defeated by US troops and Sunni tribesmen, losing control of territories.

Transition to Syria

  • 2010 Leadership Change: Abu Bakr al-Baghdadi takes leadership.
  • Syrian Civil War: ISIS joins the conflict, expanding their influence and resources.

Rise of ISIS

  • 2013 Re-entry into Iraq: ISIS returns to Iraq, dominating Anbar province.
  • 2014: Announced as the Islamic State in Iraq and Syria (ISIS); severed ties with al-Nusra Front and al-Qaeda.
  • Leadership: Strengthened by former Saddam Hussein’s officers and ex-prisoners of US-administered prisons.

Major Milestones

  • 2014 Mosul Capture: Took control of a major city in Northern Iraq.
  • Caliphate Declaration: Baghdadi proclaimed a caliphate, consolidating power over large areas of Syria and Iraq.
  • US Intervention: Initiated airstrikes targeting ISIS in Syria and Iraq.

Analysis and Controversies

  • Trump’s Claims: Donald Trump controversially blamed Obama for ISIS's rise, citing US military withdrawal.
  • Expert Opinions: Analysts argue that the US departure from Iraq in 2011 was premature, potentially allowing ISIS to consolidate.

Contributing Factors

  • Sunni Resentment: Sunni disenfranchisement under the new Shiite-led Iraqi government fueled insurgency support.
  • Former Military: Disbanding of Saddam’s army in 2003 contributed experienced officers to ISIS ranks.
  • Prison Networks: US-run prisons like Camp Bucca served as networking and recruitment centers for future ISIS leaders.

Conclusion

  • Culpability and Complexity: While direct founding claims against Obama are disputed, the conditions left post-US withdrawal facilitated ISIS's resurgence.
