In general, a wikipedia link with no additional comment does little to advance a discussion in any direction.

It might be relevant, but it's an extremely low-value comment. A good chunk of the people reading the comment (and caring about it) will already know it's describing false-flag operations.

A good way to think about good HN comments is "is there a specific point I'm trying to make". Anything that doesn't try to articulate a point is likely to be downvoted.

Thank you.
