Umm, it’s actually not as simple as that. India had VERY CLOSE relations with the U.K. since independence. Even proximity to the USSR didn’t hinder ties with the U.K. Which country was the largest export user of the English Electric Canberra, Hawker Sea Hawk, Sea Harrier, Sepecat Jaguar, Vickers battle tank ... the list goes on
But didn’t the Prime Minister of India say that the U.K is a declining power and India will ally themselves with the powers of future (what they thought is the USSR)?
