●P5 (US, China, Russia, France, UK)
●G7 (US, Japan, Germany, France, Italy, UK, Canada+EU)
●BRICs (Brazil,Russia, India,China, South Africa)
●G20 (G7+EU+BRICS+Indonesia, South Korea, Australia, Turkey, Saudi arabia,Argentina,Mexico)
The G20 is the largest club but also the least coherent. G7 and BRICs are much more coherent but they lack global authority. The P5 has global authority but it's the smallest and often unable to compromise. So?
Your vote: G7
