Hmm, I think we're talking about slightly different things...
I understand breakage of suspension of disbelief as a moment when you are reminded that you're reading a fiction.
You, quite literally, resume your disbelief, i.e. you are becoming keenly aware that you're reading fiction (compared to losing yourself in the story for pleasure's sake, aka 'suspending your disbelief').
And what I pointed out is that such moments could appear with any work, whether its elements remind you of something in real life or not.
Your initial message was
Wait, so you just said that this breaks your suspension of disbelief despite it reminding you of something that did happen in real life?
Which I found odd, since why wouldn't it be possible for a work reminding you of some IRL events to also be a work that you can't suspend your disbelief for?
That dude was reminded of Afghanistan reading this chapter. He also thinks that this chapter is poorly written which resulted in him not 'believing' it. These two facts are independent of each other and aren't mutually exclusive.
TL;DR My point is suspension of disbelief is about you and the story, not about what references the story has
Cheers
