The British Embassy in Tehran was attacked by a rent-a-crowd this Tuesday following notice of EU sanctions. Result, all staff sent home. And William Hague (Foreign Minister) gave the Iranians 48 hours to leave their London Embassy .
Not sure this helps anyone, but I suppose we get to say "They started it!" because at least we didn't storm their Embassy. This time
I'm a little more concerned about the American sanctions proposed. Controlling much?
"Experts" here suggest refusing to allow foreign companies to trade with the Iranian Central bank might lead to further disruption in the markets and higher oil prices. Which would benefit Iran, at least short term.
What with this and killing Pakistani soldiers by mistake, it's not a golden time for American diplomacy at present.
