World war three could begin soon?

Bollocks. We've got no intention of starting a war with Iran. We're using diplomacy to get our troops back. That way, nobody gets killed, British or Iranian. There's no way China or Russia would go to war with the UK over Iran. Iran pulled the same exact stunt in 2004. We got our soldiers back in THREE DAYS. Granted, this time it's taking longer, but nukes won't be flying anytime soon.
