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 never said I believed the Iranians.  And I don't.

Are you sure they're trained to confess to anything?  That doesn't really make sense to me; why give even the Iranian people, its government, and its ideological allies the satisfaction of confession?  Iran can't afford war with Britain, there isn't the most remote possibility they'd kill those soldiers.  The Iranian government is stupid and brutal, not insane.
