Having lived in countries that the US issued warnings about, I’m going to express a little sympathy for the students. As others have pointed out, they might have badly wanted to visit family and might have (correctly) felt safer than a random American tourist who doesn’t know the language/culture/geography.
Moreover, while I have no doubt that State Department warnings were utterly correct in this instance, for those of us who have been following them for years, they suffer a bit from the boy-who-cried-wolf syndrome. My understanding is that prior to the Lockerbie bombing in 1988, those advisories either didn’t exist or they were much less detailed/cautious than they are now. It came to light after the bombing that US intelligence had been aware of the likelihood of an incident but told no one. There was an outcry - “lives could have been saved if you had shared that information!” - and since then the US government has been very activist in issuing warnings. (I believe I heard this story from a reliable source in the diplomatic community, but I cannot personally vouch for it so there is a chance I’m wrong.)
Anyway, I lived in Indonesia during the fall of Suharto, the financial crisis, and September 11, and in Egypt when the US invaded Iraq in 2003 - in the last two instances with a young child. The State Department warnings varied in their degree of severity during these bits of history, but definitely got pretty intense at points. For several years my husband, whose salary came from the US government through a grant to a consulting firm, got a premium for living somewhere dangerous. We thought the extra money was nice, but silly.
No way in hell would I have stayed in a place with a little child if I didn’t feel we were safe - in fact, my son and I did evacuate to Singapore briefly after Sept 11, a choice we later felt was unnecessary. My point is, things on the ground, when you know your way around, don’t necessarily align with what you read in government warnings.
Or what you see n the news, for that matter. During the fall of Suharto, CNN was ablaze with video of people throwing rocks and setting a bus on fire, implying that the whole country, or at least the capital, was going up in flames. Guess what? I lived RIGHT AROUND THE CORNER from Megawati’s headquarters (where the mayhem was filmed). I actually walked through the cinders of a charred something that was burned on the street. It was NOTHING like what you’d believe if your source of information was just CNN. Yes, there was plenty of disturbance - but it was largely short-lived, and for a foreigner quietly going about their business, it was not particularly risky. (It was terrible for Chinese Indonesians, but not us.)
I don’t mean to make light of the sacrifices made by Indonesian dissidents through the decades - there were many brave individuals whose protests cost them dearly, and Indonesia is better today because they put their personal safety at risk. Still, that doesn’t mean every single person in the country was at risk - it was certainly possible to remain safe all of the times I was there (and in Egypt as well) if you kept your head down.
I’m not 100% defending the decision to travel to Afghanistan. Just as I was writing this, the New York Times is reporting casualties and deaths outside the Kabul airport. Should the students have gone? No, I don’t think they should have. But there were plenty of people who thought my family was crazy living in Indonesia and Egypt, because they information they were exposed to was so different than our personal first-hand experiences.
I’m just saying, the decision-making process was quite likely more nuanced than what some posters are giving credit for. When you’ve got to weigh a whole lot of factors, you don’t believe the news is necessarily as bad as people say it is and you also don’t necessarily believe the risk will completely extend to you, and you love people you’ve left behind, it could be a tough choice.
