It's not a theory, it's a well established fact that you can easily find on Wikipedia:

"The permanent members were all allies in World War II (and the victors of that war)"

Please stop telling me why belter's premise is wrong.

You can't debate me about a premise introduced by another person.

You have to resolve the issue with them.

I already made a comment that is based a premise (dudul's) that seems similar to yours, instead of belter's. Here:

Again, when I respond to someone, in the context of their premises, I am not adopting those premises and I don't have to defend them to anyone.

Go back and argue with the person who actually introduced what you want to dispute.
