A bold and ugly move but one that may have saved a lot of civilians (at the cost of a lot of invading soldiers). But as they say: In love and war .... naturally Starfleet won't see it quite like that. And one obvious downside to all this ... the Cardies will be mad as hell now. And who are they likely to punish for this preemptive attack? This is very likely to get way more ugly before it gets better.
