Crashing airplanes into buildings sounds like a problem in theory, but didn't seem like a real threat people really had to react to, so the preventative measures failed.
The biggest reason 9/11 happened was that people in power didn't really care to have it not happen. It was a boon for the Bush Administration, making it way easier for them to achieve their foreign policy. The very people responsible for preventing it to some extent care about the lives of Americans, but they also care about their careers - rocking the boat by criticizing the way intelligence work was conducted in the American government may or may not have saved 3,000 American lives but it may well have gotten the criticizer fired.
The same thing is happening on a smaller scale right now in Gaza. The murders of three Israeli teens allowed the Israeli state to achieve their policy objective of a military assault on Gaza, killing over 150 Palestinians so far. This corresponds to the 3,000 American deaths leading to the deaths of over a million Iraqis, displacement of millions more, and many more deaths and destruction across the Middle East.
I don't agree with "eye for an eye" justice, but even the most staunch Old Testament advocate can't possibly agree with "burning a town down for an eye". This is a bit tongue in cheek, because neither the American nor Israeli state cares about revenge or justice - they care about their degree of power and control. Everything that happens, whether it's 3,000 dead or a mere 3, is an excuse to implement another power move.
