NWO is not a conspiracy theory any longer. This exact terminology is openly used by many politicians now, demanding for a NWO. Depending which bubble you live in, you have not seen any or only too little such speeches.
It never was. Conspiracy nutheads just took it for them, and gave it their own evil twist. They always take something and see the evil option in it, and sell it as some fact which never was there. A similar thing happened recently with the term "Great Reset".
But the simple truth is, we always strive for a better world, so aiming for a new world order is something totally normal happening. Nobody thinks the world today is flawless.

There is no order in this world, except the laws of physics, "Me!" and some love.
