Iran has pirated 2 British vessels. One Liberian flagged, one British. I am confident that got the British a bit concerned.
But its British ships. The US did not do big bad stuff against those muslims, so its not an ok responses to our meanness. Being British, I am confident that will make things much much easier for France, Germany and all the rest over there to back and join the upcoming unpleasantries.
Either convoys and escorts or a squad or 2 of marines on each boat with a bit of air support nearby. I suspect the latter will be more productive.
