To all have not read any previous post's in regards to this thread.
I will say one thing,having sailed up the Shat Alarab River and knowing how wide it is between Iraq and Iran I can't see
how they strayed into Iranian water's
The Shat Alarab river is the final confluance of the Tigrase and Uphratese River's,on the east side you have the Oil Refinerey complex of Kuromsha and another which I forget the name of which both are huge. on the west side(Iraq)is or was desert.
This river is why they had the War as it's Iraq's only gate way to the sea beside's Umqasar.
