Frog Blast the Vent Core!
I just recently reread fleet action and HOTT and was thinking about the grand fleet that was destroyed in orbit around kilrah. If it had not been for blair, it seems there would have been no chance of confleet defending earth against its combined force (hell even a single dreadnaught could ravage several task groups) and considering that the fleet would have dreadnaughts, the eight remaining hakagas, and some new bhantkara carriers, along with hundreds of escorts. Confleet even if it rallied all its forces like tolwyn had done before sirius and terra, I don't think they would be able to stop them. Maybe bloody them a bit, but if not for paladin's little secret ops earth would have been the site of the sivar cermony in 2670.
