Losing the political aspect will hurt the integrity of the timeline in the long run. Star Trek feeds on political commentary and it would be a real shame if we see stories in the movies or TNG that have no context from stuff like the latest Israel-Arab War or what's happening back home.
Plus it's clear that the United States is going to intervene on behalf of the Palestinians and try to prevent a genocide from happening, so it's not like it's a shitty dystopia anyways. Maybe it'll be the divergence that some Americans need to wean themselves off of the "Israel is always right and can do no wrong" discourse that's popular OTL.
Speaking of Israel, I wonder if alt-Bajorans will become a more belligerent and militaristic power in the timeline as a result of the butterflies. There were always hints of this IOTL but DS9 made them fairly sympathetic aside from villains like Winn Adami. Would be interesting to hear stories where the Bajorans were oppressed yet they have learned nothing from the occupation, doing it to some other alien race instead, prompting the Federation to respond like the United States did.
So glad that Uhura's love with Scotty gets an arc instead of being a minor thing that happens in the movies.
I included some pretty awful world events that were either worse ITTL or didn't happen IOTL. I guess stepping on the landmine that is the Middle East damaged me a bit.
--Longer Vietnam War (lasted until 1976 with full US involvement until 1975 ITTL)
--Czechoslovakian war of resistance against the USSR (1977-1982)
--Berlin Crisis of 1977 (US-USSR standoff)
--A longer economic stagnation in the USA (pretty much the entire 1970s)
--Andropov leads the Soviet Union from 1977-1983
--Gorbachev deposed by Gromyko
--Another Arab-Israeli war
The grittier reality ITTL allowed a "Starfleet Intelligence" idea to become a series and a very popular one. As for the Bajorans, I haven't gotten much into TNG yet (let alone DS9) but I could see them as more militaristic than OTL.
As for Uhura and Scotty, that will be a major part of Star Trek V. In fact, that movie will start with their marriage
The US will make its feelings known in the UN and through diplomatic back channels to Jerusalem. President John Glenn made some serious mistakes throughout the entire process and now he has to course correct. We will eventually get some sort of peace but it'll be different than OTL and perhaps the Palestinians make out better (because the plan is to give them equal rights within Israel and the West Bank which is not what is happening IRL). Basically, the cost of winning the West Bank means the US forces Israel to give the Palestinians citizenship
