So Muslim/British colonialism had zero/little effect and India to day is exactly as it would be without those bad interventions? Please read up on the Buddhist concept of 'dependant rising' (hint it comes originally from India so is ok for you to study) and see how the whole world is dependant on everyone else, always. The fact that the Brits carved India up into India and two Pakistans is a big influence shoved down Indian throats and it still lingers now as a part of Indian life/thinking/strategy. Imagine how powerful India would be to day if its borders were as per before the Brits arrived. The Congress Party/Neru etc were very much against the Apartheid splitting up of India, for good reasons. Another effect of Brit colonialism is the fact that when they arrived India was the richest economy in the world and when they left in 1948 it was almost bankrupt. Imagine how powerful/dominant India would be now without Brit theft colonialism.
