In the last episode of Doctor Who (Dinosaurs on a Spaceship) we see the ISA launching missiles at a spaceship on a collision course with the Earth. It's the year 2367.
At first I thought that ISA stood for "International Space Agency", but seeing that everyone there was Indian, it seems that it stands for "Indian Space Agency". This would imply that India became a global super power in the 24th century seeing as they are in charge of global defense and not the Americans.
Am I correct in my assumptions?
Also are there any previous references to India becoming a super power in that timeframe in previous episodes? (maybe from the old Doctor Who series - which I haven't seen)
