India is soon gonna become the most populous country on earth, and it is also the 6th country by Nominal GDP, soon to be the 5th, and the 3rd country by GDP PPP.
Japan has been leading the world in techonology advances and creation. It is a major hub for everything digital. It is also the 11th most populous country and the 3rd by Nominal GDP.
Brazil is a giant in any way imaginable. It is the 5th latgest country in terms of both population and area (even though i the last one doesn't have much importance) and the 8th in terms of Nominal GDP.
Germany is also an economic monster. With more then 3 Trillion dollars in Nominal GDP it is the 4th biggest economy in the world, and THE biggest one in Europe, bigger than the UK, France and Russia. It is also the 3rd most populous country in Europe after Russia and Turkey, and 19th in the world. Keep in mind, (West) Germany was still the biggest economy in Europe even before unification.
Ignoring the importance of these countries in world trade and history, is a mistake. There aren't any other coutries, other than ones already in the security council, that can be compared in anyway to these. Maybe Indonesia and Mexico. MAYBE.
I tried to find a reason for why this hasn't yet happened, and the only thing I could find is "it didn't come up" or something. Is there a reason for them not being in? I do not see a reason.
EDIT: I've found a lot of people saying that there shouldn't be permanent members of the security council in the first place, which I find as a delta worth argument and I have REALLY changed my view on this. For real, a full 180.
EDIT 2: Japan's constitution tehnically doesn't allow it to join the permanent security council so you can cut Japan off the list
CERN, the European Organization for Nuclear Research, currently has 22 Member States and 4 Associate Member States.
At the 182^(nd) session of the CERN Council, a resolution was passed which approved the admission of India as an Associate Member State:
> The Council decided, by consensus, to approve the Resolution set out in document CERN/3274/RA pertaining to the admission of India as Associate Member State of CERN, in accordance with the provisions of document CERN/2918/Rev., subject to the signature and entry into force of the Agreement annexed to the Resolution.
Typically it takes the better part of a year for the agreement to come into force, so India could join the ranks of Serbia, Cyprus, Turkey and Pakistan in summer 2017. NB: this timescale is just my personal guess.
