Confessions of British Sailors

The "confessions" from British Naval officers that they had indeed entered Iranian waters leave me confused.  Are the sailors being coerced by threat of torture or death?  Shouldn't they have the courage and training to call such a bluff?  Or did the Iranians somehow convince them that they were in fact mistaken and had entered their territory? Or is there a third explanation, that they actually did fuck up and stray across the border.

Which is it /pol/?

I believe this is the type of escalation that Bush and co has been after all along, its the old Gulf of Tonkin maneuver. The waters between iran and iraq is at least disputed and the only reason for foreign war vessels to patrol it is for provocation. What would the USA do if Venezuela patrolled the waters of cuba, very close and sometime crossing into US territory? Would they accept it as a common mistake, or would they detain all military personnel that they were able?
