Wow - I'm struggling to understand how you're mingling the material with the spiritual with the UN.
I find you are Not alone. The 'material/political' was mingled with the 'spiritual' in Daniel chapter 2.
There it describes a figurative huge political statue and each part of the statue stood for a different world power.
Starting with the statue's head made of gold stood for ancient Babylon.
At the feet we see described iron mixed with clay. ( they don't mix or cling together )
The feet and toes then are the bad political/material state of affairs today.
God's kingdom is His government of Daniel 2:44.
God's kingdom ' symbolic stone ' hits the statue's feet and the political statue falls.
Before this happens God will use the political/military world to go up against corrupted religion.
In other words, in the past God used political ancient Babylon to go up against those unfaithful Israelites.
In the year 70 God used the Roman armies to go up against un-faithful Jerusalem.
So, the pattern is set that God will once again use the political/military realm (the UN) to be His Arm of the Law.
Then Jesus, as king (president) of God's kingdom government (thy kingdom come ) will be the one who will establish global Peace on Earth among persons of goodwill.
