I actually am not sure whether you used AI or not. But AI, very much acts like people in the sense of bias. AI is trained with the information that is available to it. This means that if there is bias in input, you will get a biased answer--exactly like people (case in point: Trump supporters).

In this domain, there is a huge bias because everything that IRI does is hugely broadcasted but everything that the west (including israel) does is hugely filtered out through a number of mechanisms (blackmail, firing, murder, ...).

Here is how I would rank the countries that most fit that statement:

1. USA because it globally implements this to control all countries. They have an offensive approach to this.
2. Israel because although it is focused on itself, it tries to do this on a global scale
3. UK: anicdotal evidence but having seen what they have and continue to do in the middle east, they too have a global implementation on this.

I am sure that other countries also do these things. IRI, Russia, and famously SA killing that reporter in their own embassy in turkey. But because so many do this, you really need to rank them rather than list one. Where IRI, Russia, China, SA, etc. rank on this list really needs actual data rather than propaganda.

Listing IRI as the top country, only shows the bias in the source rather than saying much about IRI.
