Why does this mean possible war or invasion of Iran? Well when Iraq and Libya stopped trading oil in US dollars and switched to Euros or other currencies they were swiftly invaded, overthrown and switched back to payments in dollars.
If you ain't a clue what I'm on about or why it matters, my blog post "Petrodollar Warfare" from a couple of years ago is still relevant and will explain. http://jonnybrand.blogspot.co.uk/2013/05/petrodollar-warfare.html
Saddam Hussein sealed his fate when he announced in September 2000 that Iraq was no longer going to accept dollars for oil and decided to switch to the Euro as Iraq’s oil export currency.
The Iraq war began March 2003; Baghdad fell in April; by June Iraq was now selling oil in dollars again.
.....Good luck Iran!!!
