Why would SR want to go back to India and face trumped up charges arranged by DK et al?

Precisely. This is the way to build up "assets" in any given country.

For example, if Britain wants to build up a politically active body of Indians from Kashmir they identify people with grievances and offer them for free what other people have to work very hard for. Normally an Indian who wants to migrate to the Britain would have to meet stringent requirements, but for a dissident, the act of being a dissident is enough. The same holds true if the US wants to create a body of politically active Indians in the US who can be used to express grievances against India (if the need arises). So the US will gie asylum to homosexuals and other disgruntled people virtually without getting anything in return (unlike the average hardworking Indian engineer who goes to the US). The US then builds up political and intel assets.

But its not that straightforward. there are two confounding factors which can act as spoiler1. If India has a draconian system where US diplomats and assets are not allowed to have access to Indians - this would be difficult. India simply does not do this, so I believe this can only be changed by improving Indian internal security about how the US (or Britain) are recruiting and spiriting away dissidents to maintain a politically active Indian dissident body withing their countries

2. The second factor is a carefully built of (and decades/centuries) old reputation that the UK (or US) are the same as nirvana -and that getting there means total wealth, total freedom and total happiness. The US and the UK enjoy such a reputation in India. India on the other hand does not enjoy a similar reputation among unhappy people in the US or UK, so India finds it much more difficult to build up assets within India who can be used against the US or Britain. However this can be remedied.

Information is everything. Information is used to criticize recalcitrant and disliked nations. It has been used to build up a negative reputation of for the USSR and China. It is being used to give India a particular reputation (poverty/slavery/bigotry). The same techniques of sharing information can be used to open the eyes of blinkered Indians who are otherwise intelligent, educated and influential. They have been taught to believe that the US (and Britain) are nirvana. Opening their eyes would gradually help in exposing the reality of what is happening in the US and what actually happens to people of various colours and ethnicities who decide to stay long term in the US. In the long term this can only benefit India.
