I'm a little surprised you would not envisage India being part of this group, English and Hindi being the official languages of governmet. Although scheculed by an Indian government decision taken in 1960 to be phased out in favour of Hindi by 1975, there was such resistance from regions that speak languages of the Dravidian genre. Additionally there were considerable political problems in persuading native speakers of Gujurati, Marathi, Bengali and the numerous other regional languages and dialects to switch to Hindi, yet the majority of educated Indians speak English adequately
In recent decades the idea of consolidating on Hindi as the sole language has faded, and Indian friends living in Britain tell me it is unlikely to ever happen as the regional identities and cultures are too deeply embedded.
Add India to UK, Canada, Australia and a few of Africa's more politically stable and economically developed nations (e.g. Ghana, Kenya,) and you have a truly formidable bloc that could not easily fall US domination as the EU has been dominated by Germany.
