Only you can create your own OK--it's your choice, an affirmation you have chosen--it cannot come from others.

If you are OK,  you tend to emit this OK--ness to others and they might absorb this OK-ness.

So, if I am OK and you are OK, we can widen the circle of OK-ness--it will have a domino effect.  It's then no longer an individual thing but a communal phenomenon

. If everyone in the community is OK, there's harmony and peace.
If this communal OK-ness extends to a nation, it's no longer a communal thing but a national phenomenon.  

An OK nation is one that makes another nation feel good--this is called The OK Effect and the two nations exist in the goodwill and harmony of OK-ness.

If all nations co-exist in OK-ness, they have empathy and will shed their narrow outlook. There would no longer be conflict, dissension, ******* or war. The OK effect is highly contagious-
when a person, a community and a nation have contracted it, there will be no letdown.  

A new era will dawn as all nations would have worn the OK badge.  

This, in my view, is The Brave New World, beyond all ideologies.

The UN  will be replaced by a newly-created international body named The World Council of OK Nations.
