Iran Seizes British Tankers. Now What?

It appears I was wrong. After HMS Montrose read some Iranian Revolutionary Guard Corps fast attack boats the Riot Act last week, I theorized that tensions in the Gulf would die down and that the Montrose’s actions had proved Iran to be a paper tiger. Now, with Iran seizing two British tankers (one British flagged the other British owned), those predictions appear to be false. Why the Royal Navy escorted the British Heritage, but not these two is a question that would seem to have an unsatisfactory answer, if there is an answer at all.
