MI6 Covert Action in Iran 1953: Alleged Support for Shia Islamists Preceding Khomeini

SUMMARY

Declassified British files reportedly highlight an aspect of the joint MI6/CIA coup in August 1953 against Iran's democratically elected government: alleged UK covert action in support of radical Shia Islamists. These Islamists are described as predecessors to Ayatollah Khomeini. Specifically, some reports claim that both British and US governments considered installing Ayatollah Kashani as a client political leader after the coup. While the existence of declassified British files pertaining to the 1953 coup is verified, the specific content detailing direct MI6 support for 'radical Shia Islamists' and their links to Khomeini's predecessors remains a focal point of discussion, with some sources asserting its presence within these files.

STRONGEST CASE FOR

The declassified British files, as reported by Declassified UK and Mark Curtis, indicate that MI6 engaged in covert actions supporting 'radical Shia Islamists' during the 1953 coup in Iran. This support was part of a broader strategy to overthrow Mohammad Mossadegh and secure British oil interests. These Islamists, including figures like Ayatollah Kashani, represented a faction that the UK and US considered installing as client leaders. This demonstrates a documented history of Western intelligence agencies collaborating with religiously conservative elements for geopolitical ends, which in turn inadvertently paved the way for later Islamist movements.

STRONGEST CASE AGAINST

While declassified files confirm MI6 and CIA involvement in the 1953 Iranian coup, the interpretation that these actions constituted direct support for 'radical Shia Islamists' as 'predecessors to Ayatollah Khomeini' requires careful scrutiny. The claim may overstate the degree of direct collaboration or the long-term strategic intent. Intelligence agencies often leverage various local factions without necessarily endorsing their ideology or foreseeing future political developments. The extent to which these 'Islamists' were truly 'radical' in the sense that Khomeini later was, or how directly they were linked to his lineage of thought, needs more granular evidence from the primary declassified documents themselves, rather than secondary interpretations.
