Dianavan, we have discussed the uncertainty of the line before.
It may not be something that either side would agree to draw on a map, butfor practical day to day purposes an unofficially agreed demarcation is kept to.
The Navy has been operating here for years now.
The Iranians have never before made a challenge or even a complaint.
It is not the Navy who started to make a big issue over where the line is.
The Iranians suddenly decreed that the boats had crossed the invisible line on the water and also suddenly felt so strongly about it that they captuerd boats and crew at gun point.
They also initially got the location wrong, or more likely right.
