She can't speak for the Republic Senate. She can say that Vice-Chancellor Antilles is a genuinely good man. She can say that while Count Dooku is not evil, and she expects him to continue being not evil, she's worried that he'll lose - or has already lost - the ability to be proactively good without expending effort. ...She's worried about what's whispering in his ear, really. It's not a friend or ally to anyone, not even its servants. Dooku keeps that in mind, she's sure, but...all people have flaws. Goodness knows she does, or this would have been solved long ago.
...Okay, that's not actually counterfactually possible, because she's too young to have been getting involved in politics earlier, and honestly isn't sure how she's doing this now, but still.
She thinks that the best way to get Tatooine to a place where it can stand on its own is to give the Republic and Confederacy something they think fighting over will help them secure advantages with the eventual planetary governments - to turn the corruption against itself - at least, what remains of it after what...happened on Coruscant. Most of the corruption...either left, or was removed from office.
(She takes a moment to breathe slowly after just mentioning the Battle of Coruscant. Sometimes, she wakes up in a cold sweat, having just shot Sheev Palpatine in the head.)
(She doesn't regret that in the slightest - but it's wrong, that she still had to do it.)
But really, Kina's plan is for fighting a bureaucratic delaying action, to give Tatooine, and everywhere else, time. Not a single winning maneuver. This is an interim governing procedure, with interim authority, or at least that's her intended design, here.
General Syndulla saw how she fought...what was her name, the bounty hunter, with the lightsaber, right? It's sort of like that.
Giving the Confederacy and the Republic a fight they can get focused on, luring them closer to something they won't pay attention to, stalling their attempts to strike - until they end up realizing that there's something else that they neglected, that blindsides them.
