It’s a massive threat because if you engage with Indians on friendly terms, they will lie, cheat, and steal.

That's a pretty big claim. How common do you think that is?

If you make the mistake of importing them as workers—and India often attempts to put riders encouraging this in their trade deals—they will form ethnic preference networks that will then work to consistently bring in more Indians.

I think there is a more prosaic reason why companies want to hire more Indians. They're cheap and available, and speak Engrish.

“Pushing India into the arms of Russia or China” is not so much providing them a useful ally as a massive poison pill, while simultaneously decreasing that poison’s impact on us.

I don't see Russia or China importing massive numbers of high-tech Indians. Not being Anglophone is a certain amount of protection against invasive culture from America, as well as from unwanted immigration.
