Now, in the UK do we hear voices of dissension or derision about the Raj and what England did in India to the Indians?
Arguably, the Raj was at least neutral and probably beneficial in its overall effect on the Indian subcontinent:
- it left a unified country where it had found a warring collection of kingdoms, principalities and empires.
- it left a common language. Many Hindi speakers won't speak Tamil and vice versa, but both groups can and will talk to each other in English.
- Indian Rail is an immensely valuable legacy of the Raj, along with the Post Office and a democratic system of government.
 IMO the Partition was the Raj's biggest mistake. Would the Taleban exist if Partition hadn't happened?
I have spent time in India, travelled in most parts of it, and have read a fair bit about its history. As I've never been to Africa and so have no relevant experience, I won't comment on that topic except to remark that no European countries seem to have behaved well there.
