I am thinking about rewathing the Palpatine saga just to pinpoint 2 things.

1)the absurd one-sidedness of New republic obliteration of first order

2) That the Galaxy at whole is fucked beyond any possibility of saving.

Just think of it. There are more working re-usable plaet-killer guns on one planet, then there are nukes on this one. It's only a question of ONE being blue-printed for the knowledge to become common. And at that point, a single maniac mafioso will start a chain reaction, that will result in total asteroidification of all habitable planets.
