I do think, as time goes on, and things are declassified, we'll learn more about e.g., the Iraq War than we know now. To a point, things become clearer with distance, which often renders books written on contemporary subjects outdated. But a book published today could be a decent summary of events for people who didn't live through them, or were too young to pay attention at the time. Unfortunately, one recent why I don't pay them too much mind is that most of the genre is hopelessly partisan, one way or another, and I don't know that there are any really great historians to write something timeless. But either way, I would say the insights you can glean from those books are still readily available if you're watching events critically today. Not much has changed, and if it has, it was usually for the worst. Maybe the most interesting part for many people would be the reminder that many of the same people directly responsible for those disasters are still considered respectable people today and help drive policy. E.g., Bill Kristol didn't go into some kind of exile - he's still considered a very serious person and has a lot of influence and is out there shilling the same type of thinking in a different context.
