Intelligence Community Efforts on Anomalous Health Incidents (AHIs): Foreign Actor Identification

SUMMARY

The Intelligence Community (IC) has conducted extensive targeting and investigative efforts concerning Anomalous Health Incidents (AHIs). The National Intelligence Council (NIC) issued an Intelligence Community Assessment (ICA) in March 2023, and an updated one in December 2024, which concluded that it is 'very unlikely' a foreign adversary is responsible for the reported AHIs [1, 4]. These assessments are based on years of IC collection, targeting, and analytic efforts that have not surfaced compelling intelligence tying a foreign actor to any incident [6].

However, a House Subcommittee has alleged that the March 2023 ICA lacked analytic integrity [1]. While the IC continues to investigate whether a foreign actor was involved in a subset of cases [3], and has comprehensive information on some AHI locations, no evidence of adversary activity has been found in those cases [8]. The IC's targeting capabilities include collecting communications of foreign persons outside the US under Section 702 [2]. Despite these efforts, specific foreign actors or technologies responsible for AHIs have not been identified by the IC [6, 8].

STRONGEST CASE FOR

The Intelligence Community has applied significant resources, including years of collection, targeting, and analytic efforts, to investigate Anomalous Health Incidents (AHIs). Despite these exhaustive investigations, the consistent finding across multiple Intelligence Community Assessments is that no compelling intelligence has emerged to definitively link a foreign actor or specific technology to these incidents. This suggests that if foreign involvement exists, it is either extremely well-concealed, or, as the IC largely concludes, 'very unlikely' to be the cause.

STRONGEST CASE AGAINST

Critics argue that the Intelligence Community's assessments may lack analytic integrity, suggesting that potential evidence of foreign involvement could be overlooked or mishandled. The very nature of covert operations, particularly those involving advanced or compartmentalized technologies, might evade traditional intelligence collection methods. Therefore, the absence of compelling evidence does not necessarily equate to the absence of a foreign actor, especially if the targeting and investigative efforts are misdirected or insufficient for the unique characteristics of AHIs.
