Maybe we're missing one another here but it appears you're arguing for me. Khomeini is in place _because_ of western influence/involvement, if it weren't for operation Ajax/Boot (depending on whether we're talking CIA or MI-6 naming) and the various aspects of the associated propaganda then Mosaddegh may have remained in power (I say maybe because it was quite unstable times in the early 50s Iran) and Khomeini may never have gained power.
