Thus evolved petrodollar warfare. In 2000, Saddam Hussein began accepting Euros for oil instead of dollars. This was the real reason for the Iraq invasion. Now, Iran is threatening to do the same. Can another war be far behind?
Saddam Hussein invaded Kuwait in 1990 in an effort to capture its oil fields. This led to the Desert Storm operation by the US and friends in January 1991 (First Gulf War), well before the Euro. After that, Hussein and his ideas became mostly irrelevant (Iraq was under severe economic sanctions in the '90s)...
Had the US wanted that, he wouldn't have been able to sell any oil at all
