Oryx,
that is why some conflicts arise in the world - miscommunication!

I clarify:
reengineered by UN itself: assess the world we live in today, assess the human sufferance and reengineer it in order to aim eradication of human abuses caused by human.
maybe, just maybe, this new reengineered UN will have the authority to go into sovereign nations in certain cases... I am sure, if man kind were intelligent enough to create the UN, they are also intelligent to improve it.

Now your 2nd comment. I wasn't paraphrasing you at all, let me explain it to you:
My sentence has 2 parts:
the 1st part I am agreeing with your previous post when I say "you are right".
The 2nd part of my sentence is my own addition, I am being sarcastic adding that the fact that it is convenient for certain nations to keep people poor and ignorant so they can be used (labor) for the foundations (to build) of the wealthy world.

I hope it’s clear now, that I had no intentions to misuse your valuable input.
