Long time back, Himal Khabar Patrika had published a special repoprt on Gorkhaland. I am searching for that article and put it here in case I am able to find that.

I read that Britishers wanted to give the territory of Darjeeling and other areas back to Nepal but our Rana PM at that time in 1947, thought that people in Darjeeling are educated and if they become part of Nepal, Rana Regime topples.
Today, Every Rana should feel shame because of the conduct of their forefathers. anyway, we can not do much on that front and Today, Darjeelingee People are unlikely to agree to be part of Nepal.

So, the rightful thing we can do is to help people of Darjeeling to make a new State "Gorkhaland". I think the metal/rod is still hot to hit.
