Could he have? Sure. But would he have? Unlikely, since the lack of 9/11 is a massive butterfly that changes everything.
disagree. After enough time the changes brought on by a single event tend to go away. For instance - would the us of 1975 be any different if JFK wasn't assassinated? I doubt it. Many other western countries had the same loss of confidence/trust during that time period. Look to France with May 68.
If the lack of a JFK assassination produces the lack of an RFK assassination, then presumably, yeah.
there's still no reason to think that by 1975 the following wouldn't have happened
1) great postwar economic growth eventually loses steam
2) raw number of murders triple and quadruple in the major cities - even as population decreases
3) something happens that causes people to lose trust in institutions
4) the culture shifts dramatically. Like look at how people dressed in 1963 vs 1975. It's like a century happened in a dozen years.
