I bet the Iranians dont give back the GPS equipment they have nicked, like they didnt last time, you can be sure that the British forces would have outgunned them, but its a political hot potato, the last thing either the U.S or the U.K want is an armed conflict with Iran at this moment, that would cause an escalation of conflict.

But.....they had better release them very soon, reading between the lines...there could be a very serious penalty for the Iranian captors if they dont.
