Ghost NATO?

If a small country that newly joined NATO is attacked by Russia or China, all the member countries will be involved in the war.
The problem is complicated by the involvement of post-war interests. She is Ukraine.
Problem solving that can be done only by the parties concerned will unnecessarily involve the whole world.
Then they should make Russia and China join into NATO, even if they claim different principles, the best way to avoid conflict each other?
In the first place, the Warsaw Pact mechanism of the eastern camp has disappeared, but NATO is unnecessary, and it is unnatural that it has survived until now.
You have been still there, why are you, NATO?
Looking at the representatives of each country who are dressed in military uniforms and attending, it seems that they still want to go to war.
The bloody history that has been repeated for a long time may have made it so, but I think they are no longer in a fight for the same human beings to fight for their lives.
I want you to stop the plot for the purpose of private interest!
Can you live peacefully and happily while sharing all the resources with everyone without competing and robbing, can't you?
