There has to be some intrinisic value for a currency to be a worldwide currency breh. The US dollar has been off the gold standard since the 70s, perhaps even earlier than that, and the dollar is basically fiat status right now with the trillions in debt that we have. The only other way for a currency to be a worldwide currency is the "gun". And what is that "gun"? It's petrodollars. Every f*ckin' barrel of oil has to be bought and sold in dollars. OPEC's leader at the time, was trying to usurp the US, the same way China is doing with the Africa play. He figured if OPEC could wean itself off the dollar, they could then dictate how things are run, because they controlled most of the world's production of petroleum. If Iraq starts selling oil in euros, then follows Iran, then Syria, then Libya, and then all these London, NY, and HK traders follow suit and dump the dollar for the euro, because traders make money in volatility, meaning price goes up and down all the time. If nobody needs the dollar, why trade in the dollar? And boom, the dollar becomes the ruble in a very short time. That's about as simple as I can make it. Saddam had to go for the petrodollars to keep flowing. They just assumed since they put Saddam, that they could put any patsy in there and things would continuing normally, that's where they f*cked up, trying to install a democracy in a place that has never known democracy.
