Preventing WW3 usually starts by airing grievances so the collective body can talk about said problems and come to a peaceful, diplomatic solution.

I don't think that works anymore, UN can only issue "deep concerns" (c).
The real prevention starts when the collective body deploys troops (or authorize the deployment). The last such real deployment, authorized by UN, was for Iraq (Saddam Hussein), who really could start the WW3. But you know how it's portrayed now by authoritarians, so I doubt we will see any real action from UN anymore until the WW3 happens.
