The fact is that the Republic already knew that the Kaleeshi were under attack, they told them themselves when they asked for help at the beginning of the war, but the Huk and his allies lobbied the hell out for them to be ignored... And they did the same when the Kaleshi retaliated they bribed the hell out of the Republic to paint the Kalseshi as the aggressors[X] How dare he?
IIRC in canon the Huk managed to convince the Republic that the Kaleeshi were the aggressors and got the Republic to intervene on their behalf and crush the Kaleeshi rebels under Grievous, and here Grievous is risking exactly that outcome by threatening orbital bombardment of Huk civilians in full view of the Republic's diplomats. It's exactly the opposite of effective strategy.
So in canon, the Orbital Bombardment thing was irrelevant since the outcome of it had already been decided in Coruscant, and the Truth was not going to get in the way of good business with the Huk
