The Petro-Dollar War
The first thing the US did when it invaded and took over Iraq was
reverse Saddam Hussein's recently policy of demanding Euros in
payment for his countries oil.
Some think that's what the war was all about and that Iran's
insistence on receiving Euros for its oil is the real reason that
country has been targeted.
Dollars? Euros? What's the difference?
The difference is this...if you are the dominant currency, you can
support your lifestyle and war machine by printing more when you run
out.
Take that power away and there will be a very economic painful
dislocation in the US.
