With a million dead, the Iran-Iraq war is ranked on this website as the 18th worst atrocity in the history of the world. I was in Iraq during the first two years of that war. I had no idea at the time that the Kingdom of Saudi Arabia and Kuwait were lending money to Saddam to fight that war. The loans (Saddam thought it was a gift) were on top of Iraq's own money Saddam spent on the war. Kuwait still wants all its money back.
The pic is a little reminder to those who still believe that Saddam could not possibly be close to the Saudis, because one was secular and the other is not.
