How did the Rebellion, weaker than the New Republic, ever manage to even challenge the united Empire then? The major Rebellion lasted like seven-ish years or something from the signing of the agreement on Corellia by the three biggest rebel groups to create the Alliance, to the battle of Endor
Did you not watch the movies and read the EU? Most of the Empire died fighting itself after Palpatine died on Endor. Dude, this is basic history.
Daala's opinion is her biased opinion. She also got bitchslapped every time she tried taking on the New Republic until she played politics to become Chief of State of the GFFA or whatever, and then she failed again, she wasn't exactly competent tbh
Daala's not wrong in that Imperial infighting was bad for the Empire. Sometimes, a broken clock can be right twice a day. She was, after all, Tarkin's protege for a reason.
From what I remember, Disra thought the New Republic could be beaten because revealing the Bothans glassed Caamas would tear it apart and the "return" of Thrawn would give the Remnant a shot in the arm, not that the united New Republic was overstretched and exhausted militarily. Politically, yes. Militarily, no
5 fleets of 500 ships each patrolling an area that is at least, half the Empire's turf? No, that is overstretched.
And yes, I pulled that figure from the books.
The Empire was fully intact by your definition and couldn't crush the Rebellion before Endor
They were winning most major conflicts. Garm Bel Iblis explains in the Thrawn Trilogy that he didn't join the Rebels proper because there were so many news segments of them getting their butts kicked by the Empire. Hell, the X-Wing game starts off with a cutscene of the Empire bombarding and seizing a rebel base. Hoth wasn't the exception; it was the norm. The Rebels lost Yavin for the exact same reason: they can put up a fight, but not forever.
Speaking of Endor, the only reason that was important was because the Emperor died. If he managed to escape, he'd just rally the Empire's forces again and charge full-throttle at the Rebels. And the only reason he died was because Vader had a last-ditch change of mind. Meaning that if he didn't, or if Palpatine wasn't stupid enough to turn Vader's kid against him, then the Rebels would've likely lost, as Thrawn notes that they were winning thanks to Palpatine's Battle Meditation; something which went offline when he was distracted with the Skywalker baby-mama drama.
Hell, they had to invent Battle Meditation as an excuse as to why the superior Imperial fleet didn't win. Even the EU writers knew the Empire should've won Endor based on numbers alone.
You don't like that the Empire lost so it's unrealistic. Whatever. You think the ideal situation for the Empire is realistic, because. It's not realistic for corrupt military autocracies to not have rivalries and competition carving out fiefdoms, even when the central authority is still operating. It's not realistic for an empire that controlled nearly all the known half of the galaxy, and a large chunk of the Unknown Regions, to be able to concentrate all its resources on "the Rebels." Aside from the open rebellions, large chunks of the population of ostensibly Imperial-controlled or -subservient populations (like Corellians and Duros and Fondorians and Sullustans and...) and organizations were either sympathetic to the Rebellion (like Kuat of Kuat) or aiding the Rebellion in secret (like SoroSuub and Incom) or were actively undermining the Empire (like Black Sun) or were playing both ends (like the Hutts). There were ancient enmities between planets, systems, regions, and sectors that the lid had to be firmly kept on, or the Empire would tear itself apart in galaxy-wide internecine warfare that did not even have the Empire itself as a target. The Emperor's arrogance was very well-established in rotj and the EU. There are plenty of examples in the real world of military autocracies that failed to suppress rebellions despite a lack of infighting. One of them is going on right now in Burma. The military is fully united against the rebels, always has been, it's been fully united trying to control the country for decades, and is still failing to get the job done
That's not the case. I'm merely stating what is and isn't realistic. The fact that they had to invent Battle Meditation, and the fact that they had the Empire fight itself more than the Rebels after Endor, goes to show that the Rebels won due to plot. I can like the Rebels as much as the next guy, but I still have to admit that the Empire should've won realistically, if the story has to bend over backwards and invent shit like Battle Meditation or have the Imperials post-Endor be obsessed with infighting and power struggles in order to give the Rebellion a realistic reason as to why they even won.
Because if the Imperial armada just attacked on Endor instead of having the Emperor hold them back, or if they just elected a new leader among the Moffs to lead them then resumed full-scare war with the Rebels, there would be no New Republic. And all the reasons you listed there were tiny pebbles that wouldn't have amounted to shit if the Empire remained united.
Okay fine if you want to say with the perfect conditions the Empire would have easily crushed the Rebellion, and even the New Republic after Endor. So what, those perfect conditions are what is unrealistic
Not even perfect. It would make more sense if the Empire crushed the Rebellion, THEN they descend into in-fighting once they have no outside foe. But again, the Rebels won due to plot. They had to invent reasons like the Battle Meditation going offline throwing the Imperials into chaos, or the Imperial leaders being more obsessed with warlordism and infighting, in order to explain why a galaxy-spanning army lost to a small rebel force. That literally is them winning by plot.
If I were writing a story for why the Rebels won, I would have half the Empire defect to the Rebel side after Endor. They were only kept in fear due to Vader and the Emperor, and those guys are now dead; their soldiers would be more idealistic and want to protect the galaxy, and they saw how the Emperor and Vader abused their power and used the military to keep the galaxy under their thumb, so once they disappear and these officials no longer had to worry about being strangled through the Skype call, they immediately defect to the Alliance and hail Leia as their Empress, as compensation for her losing her homeworld to Tarkin's Death Star. Then the Rebels would have the firepower and numbers necessary to take Coruscant and run the galaxy.
