Sort of. I think there was an effort to put a rules-based framework, still skewed towards the "great powers", but a framework nonetheless.
Invasion of Afghanistan only happened after diplomatic efforts to get the Taliban to surrender Bin Laden. Iraq invasion was pushed through UN. Likewise, the Balkan war in 1990s was UN-sanctioned.
This? I mean, never mind the question of nukes, I don't think anyone declared war. Iran is a buffet of pick-your-own-target, in the middle of a negotiation that was supposed to end the nuclear program peacefully. I'm not saying it because I like Iran (I don't) but because it sets the tone where countries just do what they want, if they can get away with it. It's a step back from a world, where at least in theory we were supposed to stay within the frameworks of principle-based laws.
You might argue that this was always a façade only, and the powerful did whatever they wanted, bending the law around it. Maybe. But I'd like to think it set a limit to how far they can bend it. Now? I'm not so sure.
