I'll quote this one bit in particular:
And why, you might ask, did the Iranians feel threatened? Because they were planning to attack (or have their surrogates attack) the oil terminals, silly.
Iran picks up a bunch of British sailors laying detection equipment in the Persian Gulf region, and the author makes the wild (and thoroughly unsubstantiated) accusation that Iran did this because they are planning to attack Iraqi oil terminals.
The notion that Iran simply didn't like the idea of British sailors carrying out a covert military mission in Iranian waters is apparently beyond the author's infantile mental capabilities.
I agree with you it's a silly article, but even I doubt the Brits laying motion detectors in the Shatt al Arab. The Iraqi oil terminals are not in the Shatt al Arab, they are a fair distance offshore, where the water is deep enough for VLCCs to approach. If the Iranians really wanted to launch an attack of some sorts against the terminals, they have plenty of coastline that belongs exclusivly to them. No need to use a waterway that they only control half of.
