Unknown unknowns are definitely difficult to predict.

Psychoanalytic philosopher Slavoj Žižek says that beyond these three categories there is a fourth, the unknown known, that which we intentionally refuse to acknowledge that we know: "If Rumsfeld thinks that the main dangers in the confrontation with Iraq were the 'unknown unknowns', that is, the threats from Saddam whose nature we cannot even suspect, then the Abu Ghraib scandal shows that the main dangers lie in the "unknown knowns"—the disavowed beliefs, suppositions and obscene practices we pretend not to know about, even though they form the background of our public values."

I believe in that speech Žižek was just referring to assumptions -- i.e. the things we don't know we assumed, but are acting on subconsciously. The famous slide of how to invade Iraq made the invasion look simple and definable -- but in fact that assumption proved very wrong.

" just referring to assumptions -- i.e. the things we don't know we assumed, but are acting on subconsciously"

This is much, much more than "just assumption" to Zizek. In fact, this is what he refers to as ideology and it's basically the main subject he is known for

Sure, assumptions are shorthand ideology for the brain.

Invading Iraq was easy, the problems all arose at the “okay, now what?” level.

That's part of the classic formulation, which dates to the 1960s, and which I first encountered in the 1980s in print. It's effectively a "consultant's matrix' of "known" and "unknown", giving a matrix of four elements: {KK, KU, UK, UU}.

The notion of unknown knowns strongly resembles the apocryphal Mark Twain quote; "It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so". (There's no apparent proof he'd said or written this.)

They just quoted the wikipedia article (without attribution). It, in turn, cites the link above.

Reading that quote by Rumsfeld only reminded me of Joey Fromm friends: https://youtu.be/LUN2YN0bOi8

Worst, however, may be the unknown knowns.

And this is Rumsfeld's only positive contribution to society: A pithy little "(un)known/(un)known" quip

It's hardly original to him. It's a negative contribution, as a lot of dimwitted people disavowed the idea of unknown unknowns after he said that. It's actually a valuable concept.

A more useful quip of his, in my opinion, is: "You go to war with the army you have, not the army you might want or wish to have at a later time."

I find it a useful reminder at work when approaching projects with a team of mixed ability...

(I'll refrain from commenting on other aspects of his legacy.)

Yes I just can't see it happening.
