I don"t think that it has anything at all to do with Territorial Waters. The sailors / marines were taken prisoner by units of the ruling political party, not the Iranian Navy. They were hovering / loitering close by, probably for some time, just waiting for the opportunity to grab a boarding -party, and take them hostage, then humiliate them in the eyes of the world, as they"re doing now.Why ?? God knows !! Pride ?? Prestige ? "Face " ?? The Iranians are not Arabs , don"t forget----they are Persians, and would love the Arab countries to fear and respect THEM . What better way ,than to very publically humiliate Britain in the eyes of the whole world, whilst at the same time testing the USA "s resolve by demanding the release of Iranian prisoners !!?? If anything, it"s a stroke of genius !!Of course, if Britain had STRONG leadership ( Churchill, Thatcher ) then this farcical situation would either have never arisen, or would have been dealt with quickly, ruthlessly and decisively, but under Trembling Tony, the situation will probably drag on for months or years !! And what the Hell is my country doing, sending the mothers of young children out to risk their lives ( and mental health--She will never be the same, not now ) in God-forsaken and highly unstable places like The Gulf ??? What price sexual equality now, ladies ???
