The New Security Council would consist of;
The U.S
India
China
Germany
Russia
Saudi Arabia
South Africa
Brazil
Britain
Australia
Japan
There is no veto power, and Ties are broken by the Secretary-General
Saudi Arabia? Hell no.
Why Australia?
For the Saudi's I'd rather have no one from that part of the world... But I figured I had to have somebody, and it was either Saudi's or the Iranians and I see the Saudis as (currently) the lesser of two evils). As for Australia, I was tempted to give that spot to Argentina, Mexico or South Korea... and I guess replacing the Saudis with someone from that trio still makes sense.
