Correct, I understand the definition of worship here, however the Bible here says this control is total. The UN and every government strives to complete domination, yet they cannot attain it, because there are too many captains on the ship, cooks in the kitchen etc.
The British Empire for example had more power back in its day over more people than the UN today does. I would suggest starting from scratch on all these interpretations, as remnants of WTBTS interpretation often poisons the mind.
The UN is totally ineffectual, as is any congregation of people. The UN and WEF and similar organizations is an extension of socialism/communism into the world of politics, by definition it must fail in a capitalist world. Hence the beast cannot be based in those, it must be based in a unified approach to something else, capitalism sets up markets in opposition to each other. Therefore I can’t believe that the beast is pointing towards a modern day body politics or one that has arrived yet.
There once was a body politics that had captured the entire ‘known’ world, and that was when this scripture was written, the Romans seemingly had captured all of the known world. Hence I believe the interpretation must be in its own day when scripture was written and the beast was a form of government (Roman senate) that breathed life into another form of government (the Roman dictator).
