However, with this hypothetical besieged planet, Starfleet can tightly control the information that comes out of it - even moreso if they don't land troops on it. Ship to home communications can be tightly censored, and communications from the planet can be jammed. Furthermore, any civilian ships straying near the combat zone in hopes of picking up a scoop can be intercepted and detained, and their captains charged with failure to file a flight plan.

The truth won't come out until after the war, and at that point I'm sure an adept politician could whip up some other minor crisis to distract the public attention until they forget about it.
Besides, it's not like they're going to be incinerating the cities and civilians en masse; just the major space-capable military resources.
