I saw somewhere where a person said
“America seemed to be going forward. Then 9/11 happened and we threw all of that away out of shock and hurt.”
That stuck with me. But as I’m not American and barely old enough to remember a pre 9/11 world, I was curious if you think that thought process holds any weight?
9/11 was definitely a watershed moment for America, although the circumstances leading up to 9/11 started probably around the time of the Iranian hostage crisis of 1979, which then led to Reagan's election. The post-Vietnam, post-Watergate era led to a certain anti-militaristic viewpoint, as well as one of greater tolerance, but once footage of Iranians burning our flag, saying "death to America," and leading blindfolded hostages out in front of angry mobs, any chance for a peaceful, tolerant America pretty much evaporated at that point.
Reagan also appealed to the so-called "moral majority," which was a reaction to various movements which came out of the 60s, believing that America was becoming too immoral and permissive. It should be noted that a lot of the leading Republicans up until that time were far more secular and felt that religious right was too radical. Even the grandfather of conservativism, Barry Goldwater, somewhat eschewed the religious right, although not so much as to abandon them entirely.
In the ensuing decades, there was a resurgence in American militarism which continued even after the end of the Cold War, which eventually triggered 9/11, which led to a doubling-down of the same process Reagan set in motion 20 years earlier.
