Intelligence Report: Deadly attacks in Australia and Syria show a diminished ISIS is still a threat

1. BLUF (Bottom Line Up Front)

Despite a significant decline in operational capacity, ISIS remains a persistent threat, as evidenced by recent attacks in Syria and Australia. These incidents highlight the group’s ability to inspire and possibly coordinate attacks globally, though their direct involvement is uncertain. The overall confidence level in this assessment is moderate, given the lack of direct claims of responsibility by ISIS and the potential for local actors to act independently.

2. Competing Hypotheses

  • Hypothesis A: ISIS is directly coordinating and executing attacks globally, as seen in Syria and Australia. Supporting evidence includes the presence of ISIS flags and literature with the attackers in Australia and the U.S. and Syrian governments blaming ISIS for the attack in Syria. However, the lack of official claims by ISIS and the decline in global attacks contradict this hypothesis.
  • Hypothesis B: Local actors with grievances are independently conducting attacks, inspired by ISIS ideology but without direct coordination. This is supported by the decline in ISIS’s global attack numbers and the absence of official claims for the recent attacks. The praise from ISIS-linked accounts could be opportunistic rather than indicative of direct involvement.
  • Assessment: Hypothesis B is currently better supported due to the lack of direct claims by ISIS and the trend of declining attacks. Key indicators that could shift this judgment include new evidence of direct communication or coordination between ISIS leadership and attackers.

3. Key Assumptions and Red Flags

  • Assumptions: ISIS’s operational capacity has diminished; local actors can conduct attacks independently; ISIS-linked social media accounts may not reflect official positions.
  • Information Gaps: Direct evidence of ISIS coordination in the recent attacks; the extent of ISIS’s current global network and resources.
  • Bias & Deception Risks: Potential bias in attributing attacks to ISIS without claims; risk of overestimating ISIS’s current capabilities based on historical data.

4. Implications and Strategic Risks

The persistence of ISIS-inspired attacks could lead to increased security measures and strain international relations, particularly in regions with active ISIS cells. The group’s ability to inspire attacks without direct involvement complicates counter-terrorism efforts.

  • Political / Geopolitical: Potential for increased military operations in ISIS-affected regions, impacting regional stability.
  • Security / Counter-Terrorism: Need for enhanced intelligence sharing and monitoring of radicalization channels.
  • Cyber / Information Space: Increased propaganda efforts by ISIS to maintain relevance and inspire lone actors.
  • Economic / Social: Potential economic impacts from heightened security measures and social tensions from perceived threats.

5. Recommendations and Outlook

  • Immediate Actions (0–30 days): Increase monitoring of online extremist content; enhance security at potential target sites; improve intelligence sharing with allies.
  • Medium-Term Posture (1–12 months): Develop resilience measures against lone-actor attacks; strengthen community engagement to counter radicalization; invest in counter-propaganda initiatives.
  • Scenario Outlook:
    • Best: Continued decline in ISIS attacks; effective counter-radicalization reduces lone-actor incidents.
    • Worst: Resurgence of coordinated ISIS attacks globally; increased geopolitical tensions.
    • Most-Likely: Sporadic lone-actor attacks inspired by ISIS; gradual decline in ISIS’s influence.

6. Key Individuals and Entities

  • Aaron Zelin, expert on ISIS and fellow at the Washington Institute for Near East Policy
  • Renad Mansour, research fellow at Chatham House
