I’ve been saying this literally since before Dreadnoughts were even a thing. The fact that they are makes it all the more approachable. The fact is the destruction of the Senate is important. What isn’t is the destruction of an entire star system.
Especially because in-universe, planet destroying superweapons clearly do not friending work. Why the bad guys would try it a second time, let alone a third time, let alone a fourth time, is beyond me.
