I mean, the world is going up in flames. That is a pretty big thing that is happening. Those 5 countries and their mutual defensive pact allies are responsible for a majority of global emissions that are heating the planet to the point of uninhabitability.
Billions of people will die violently, for a large part because if the UN-mediated stability of capitalist global trade and its unlimited industrial capacity to make the planet uninhabitable.
The UN with its veto system has effectively prevented non-permanent UNSC member nations from coming to binding agreements and pushing them on the privileged few. 6 billion people from across the world matter less than 70 million British people, even though India and Pakistan both have nukes too.
Yes, and we do.
