That was in 1988, quite a lot has happened since then. In the aftermath of it, Gaddafi was cowed and sanctioned. Libya became less far provocative and accepted blame for the incident. By the mid-00s, it seemed like the demise or reform of oppressive regimes like Libya was inevitable. America took Libya, still under Gaddafi, off it's list of state sponsors of terror. Gaddafi's reputation never really recovered though, and that reputation probably played a role in his eventual death (nobody cared to save him.) It seemed as though other leaders of repressive regimes were laying low, hoping the same wouldn't happen to them.

What we are seeing now seems like a return to form. Obviously all of this falls well short of the political violence seen in the 20th century. That's not an interesting observation. By that standard, literally everything after WWII has been a huge nothing-burger. That shouldn't stop us from observing worrying trends in the present.
