"They were very embarrassed by our discovery of their involvement with Iraq and some very lucrative oil contracts."
I assure you there was no embarrassment, no more than the US is embarrassed for propping up the despicable Saudi regime.
Modern states need oil. France's oil security lay partly in lucrative contracts in Iraq. The US and France were both keenly aware of those contracts before the war in Iraq, and there was a very tense negotiation about them. The American position was that no existing oil contracts would be respected under the new, American-installed regime (in other words, the US was going to enhance its oil security by adding Iraq's oil to its international "safe sources").
When it became clear that the US wasn't going to allow France to retain her Iraqi oil security, France became a strong adversary of the US war, and used its diplomatic power to do as much damage as possible to the American war effort.
The US seems to have learned from the experience, and in Lebanon and Iran, now, are working closely with the French.
The discovery was accompanied by shrieks of outrage from France.
Then the SAM missiles manufactured in 2003 were found, French manufacture.
Yes, there was embarrassment.
