I am extremely surprised at the innocense expressed here.
There will be NO new permenant members at the UN. If anyone wanted one, it would have been done a long time ago. The last time this happened was when the China seat shifted from Taipei to Beijing and that's because of the US effort and an agreement by the three members of the P5. Taipei, a permenant member had no say whatsoever. Taipei, a P5 member, not only lost her P5 seat but also kicked out of the UN as the representative of China.
So, people, given the above. Wake Up. The P5 is playing you. Some members of the P5 supports you mainly because they know you will be rejected by at least one other member. That goes for all countries. I am extremely surprised that no one had taken the hint that once Stalin rejected Canada, the one commonwealth country other than Britain who came to her defense, that people actually think Japan (an enemy), India (not even a dominion), South Africa and Brazil (not even a worthy participant) had a chance.
By the same token, we rejected the Mongolia lead Central Asian Republics who have lost more soldiers than the entire Western armies combined.
In short, stop believing the P5 had any interest in expanding, they're playing you for fools ... and you're falling for it.
