Meaning of "Hindu Kush"

Wikipedia says it means, "The mountains of Hind".

Either:

1. Prager is making a huge mistake because
-he heard this somewhere from some one he trusts to know, such as someone who speaks the language and
-he never looked it up himself.

or
2. Prager is a liar.

or
3. Prager heard some explanation and mis-remembered the information.

or
4. Someone vandalized the wikipedia page and put false information there so as to shine a softer light on whoever would be judged evil

I consider (1) to have a fair degree of probability, maybe 25%. Usually Prager checks his information
(2) is utterly impossible. Remember that the word "lie" doesn't mean "making a mistake, repeating false information" without "directly intending to deceive".
(3) is more like something I would do than Prager.
(4) is by far the most likely, given what I've seen of people with an agenda saying whatever they want on articles.
