POLITICS: Composition of Security Council

In today's current geopolitical situation, two countries do not deserve to be there in the Security Council. They have a shell of a military (the SAS and the Foreign Legion amongst others are world class), their economic potential is so-so, and their population is less than what other and more deserving countries have. They will never be great again, umm... at least not in the forthcoming 50 years. Before anybody adds any new countries to the Security Council, which is ineffective anyway, those two countries should be kicked out. Old men should not do some things which are detrimental to their health.

No prizes for guessing who they are.

Also, Japan's population is getting too old for it to be considered in the Council. What is the use of being a permanent member? Except maybe for pride and one-upmanship against China. I hear they don't like immigrants preferring robots to do their work, and encouraging their women to marry and have lots of kids.

I am guessing a lot of it boils down to population demographics.
