Here's a thing. Colleagues of mine want to sell food and medical supplies to Iran, but they are refraining because if they did then I, as a senior member of the company, could be prosecuted by my own government and/or abducted by the Americans to face trial in a country I've never visited. To re-cap, western sanctions against Iraq pre-2003 led directly to the deaths of 500,000 children. This is the kind of stuff we attribute to the Nazis (and screw Goodwin's Law on this occasion), Soviets or Chinese, not us 'civilised' people in the west.
Why do we believe it makes a difference whether it's Obama or Romney, Cameron or Miliband, Bill or Ben that takes office after our show elections? It pains me to admit that we, the West, are a bunch of stinking hypocrites happy to starve innocent people for political objectives. These are not the values of our people but believe me, trying to explain that to folks living outside our bubble is...challenging.
I'm a realist and if Iran develops nukes then for our own preservation we need to bomb that programme back to the stone age, but it doesn't justify what happens to innocents in our name. Obama or Romney, Bill or Ben, it's all the same shit and the sooner we, the people who actually uphold our values realise it, the better.
