Well, sure France enabled Saddam.
Saddam gave France cut rate oil, and France gave Saddam money for it. Hard currency aided Saddam. No question about it. Whoever traded with Saddam aided Saddam.
The French purpose wasn't particularly to aid Saddam, but to protect France's cheap energy supply. The French propped up Saddam's regime, to a point, in order to keep that oil flowing.
Now let's talk about the horror, oppression, torture, and terrorist funding from Saudi Arabia, and the degree to which the United States will absolutely prop up the Saudi regime no matter what, in order to preserve its oil interests.
Countries do what they need to do.
