Consistency has never been a key factor in US foreign policy. It doesn't matter if there's a Democratic president, or a Republican one, the double standard employed by both always been the same.
Take today, as an instance. Secretary of State Hillary Clinton announced sanctions against eight Iranian officials for human rights violation following a crackdown on protesters after last year's elections. On the surface it sounds good, not just more posturing designed to soften the television watchers up for an attack on Iran.
In the meantime, the UNHRC says Israel used incredible violence against a Gaza Aid flotillaviolated international law by storming the flotilla and killing nine human beings, including an American in execution-style killings, and what does our country do? It criticizes the report as 'unbalanced'. The truth is, the only thing unbalanced is our foreign policy, which seeks to condemn one act of brutality, while defending another.
Now one case is set to go to the International Criminal Court, which the US opposes, mainly because between Iraq, Afghanistan, and the crackdown on the Gaza strip, American-Israeli exceptionalism rules the day. We can torture, kill, and maim whom ever we so please, as we are better than the people living over all those preciou natural resources the Corporate Idiocracy needs to keep it's followers happy and buying more useless things, giving up their time and money to make the incredibly wealthy, more incredibly wealthier.
I don't suspect this will end anytime too soon.
