Uh? The French literally convinced most of the UN members (except the United Kingdom) to NOT support the USA in invading Iraq. The French representative at the time directly confronted Colin Powell about the supposed "proofs" on WoMDs. They also predicted exactly what is happening today: increased terrorist risk, geopolitical instability, economic fallout etc. You can see the famous speech of Villepin at the UN on YouTube. This how the war on Iraq was deemed as illegal by the United Nations Secretary-General Kofi Annan at the time.
Fun-fact this is also when French bashing started to rise in the US, coming from politicians but also throughout pop-culture.
Oh? Is this one of those symbolic UN votes that amounted to nothing? I was referring to actual sanctions all the western allies are putting on Russia right now. Options that have teeth. But no one dared to do that to America.
