Pretty unlikely that Ahmadinejad was the specific culprit way back then. But what's the difference? Hostage-taking is not some secret technique that's only known to those who've done it before. It's obviously a standard part of the Iranian playbook, and I personally think we're in for a long haul on this one. It's a paranoid regime, and the taking of the hostages was obviously a calculated move.
For our part, obviously we don't have enough troops or enough standing in the region or in the world to exert very much direct physical or moral influence. Have you noticed that the US government's silence is deafening on this issue?
I know that--governments and politics aside--our hearts are all with our Brit cousins and that we look forward to the hostages' safe return.
