The other DrC and I visited India recently. Particularly in Bombay (some call it Mumbai) we saw much the Brits left behind of which they can be very proud.
It may not be "politically correct" to honor what Britain accomplished in India; however at COTTonLINE we do. To see an article which agrees with our view, see this by Adrian Lee in the Express (UK).
As Lee says, that which ties India together is what the British left behind: democracy, the common English language, the railroads, the courts, the civil service and the Indian Army. In short, all those things which tie together a group of peoples speaking many languages, worshiping many gods, following many customs - all of those "tie together" things India got from Britain.
