They chose Giuliani instead.
If their bravery had caused a proper response, similar to how Norway responded to that mass-shooting, then it'd be worthwhile to note. But despite their bravery, that "garden-variety terrorist" has succeeded in scaring people into allowing their government to expand powers.
And the dismissal that it doesn't matter because he didn't think it'd work out - that's just idiotic. Do we disqualify scientists from the other Nobel prizes because "they really didn't think this experiment would discover anything"?
I'm just pointing out their terrible use of rhetoric and lack of logic.
Hitler was Time's Man of the Year in 1938, based on his foreign policy maneuvering at that time. Despite the much greater enormity and historical impact of the Holocaust, he wasn't put there in 1945 or any time since.
Time editors are not going to expose themselves to that level of social anger. No matter how many times they say "Man of the Year" is not a reward, it still has that connotation in a lot of people's minds.
Also, he didn't scare people. US government did by waiving the terrorism banner for all these years.
