Assuming that you know about Rules Of Engagement, how they’re applied to different conflicts and why, you would know that there is always a reason behind them.
Yes, maybe a theory that seems paper thing on the surface, but i’ll go with my hunch. It maybe a Brit motive, maybe not, but i’ll stick with that belief at the moment till proved otherwise......
Of course there is. However a high-up Brit admiral (IIRC) stated in at least one publication that the ROE regarding Iran were to avoid escalation.
I've also read these ROE are actually UN ROE that Britain has accepted. The responsibility for the ROE it imposes is Britains of course regardless of where they originated, but I'm thinking Britain is mostly trying to avoid being the cause or being accused of being the cause of an international conflict through provocation.
The same rules don't apply to Iran, obviously...
