Iraq was about securing the US Dollar as the reserve currency for trading oil, not about securing supply to Western Europe. Saddam was threatening to start trading in Euros - he wasn't threatening to cut them off.
“Unthreatened” by regional conflict that spirals into affecting regional output more than anything explicit like turning off the taps.
And I’m sorry, but I personally still can’t/won’t do petrodollar discussions on the internet. It’s a perfectly valid reason for US involvement here, but I have been deeply scarred when it comes to good faith on this subject.
