You can Google around for articles on what places like Iran and Afghanistan used to look like. They're instructive. Then read up on the history of those countries, and how things went wrong.
It's also instructive to pay attention to the names. Some of them are going to jump out at you, and at least a couple times you're going to think "wait, isn't he the bad guy" when, once upon a time, some recognizable name was "on our side" (but really was on his own side all along, and willing to play at doing a major power's bidding in order to get funded/armed/maintained in power/etc.).
And some of the names of the foreign-policy wonks are going to get eerily repetitive, and you'll wonder how these guys managed to stay cozy with administration after administration despite their track record of literally leaving desolation around the world. Worse: you're going to read their bios and find out some of them are still in positions of power and being taken seriously today.
