Trading in a different currency means you are deliberately annoying another country?
You miss my point. It's something thats easy to state an intention to do, knowing that:
a) It probably can't happen easily so you don't even need to do it
but;
b) It'll really wind up your enemy by saying it
Ask yourself, why should say Iran, or Venezuela, or other countries, trade in a currency of a nation which has publicly insulted and offended you? Why SHOULD Iran or Venezuela et al, use USD?
I'm not disputing that - but in reality, it's far more difficult to acheive and suggesting that these states were 'invaded' because of this intention is a bit tin-foil-hat - nobody has suggested invading Venezuela for example!
Why would you want to use that currency?
Because the rest of the world does and the rest of the oil market does. I know, it's a bit of a catch 22 situation.
I'm not even saying my personal beleif is that the Dollar should be the oil currency, either. But barring a fullscale collapse of the dollar or a concencous from all oil producing nations and OPEC (And therefore, Saudi) it's inevitable it will remain so.
