Lol. Why are you even following this franchise if you think hope is a weak thing? Take a look at the title of the first film in this franchise. The part that comes after Star Wars… In any event, yeah, the Rebellion is still weak vis-a-vis the Empire at this point. They don’t have the firepower or the numbers to take on the Empire full-on. Indeed, we see that play out in ANH where the heart of the Rebellion almost gets wiped out by the Death Star. So yeah, they’re weak. And many of them want to be in more of a position of strength before making making a major attack on a military installation. That’s exactly how most guerrilla movements have operated throughout history - whether it was Che and Castro, Ho Chi Minh or Giuseppe Garibaldi. Small attacks until you’re ready for the big one.
"And know this, the day will come when all these skirmishes and battles, these moments of defiance will have flooded the banks of the Empire's authority and then there will be one too many. One single thing will break the siege." - from Nemik's Manifesto
Just here to say, Raddus is still a chad despite him only having a small say in the council meeting; my admiral is radiating peak Rebel energy.
