Big organization like NATO has to provide solution to the conflicts since they claimed to be a peaceful bloc. But from what we could see is that they offer non, for them its all about control which we can see thru the sanctions and regime change.
In this conflict, only Russia seem to be open to negotiation. They even warn that Ukraine's NATO entry will result to war but they still pushes it.
Now that each party have been gathering allies already, its becoming harder to prevent.
"NATO was constructed on the - with the reason, whether one believes it or not, that it was going to defend Western Europe from Russian assault. Once the Berlin Wall fell and the Soviet Union was beginning to collapse, that reason was gone. So, first question: why does NATO exist?" - Noam Chomsky
Let accept the fact that war lord has created so much destruction in the world.
This is sheer propaganda what wheat war is going to happen - nothing like this will ever happen.
