Yeah, the Blakists intentionally revealing the Blood in their midst relies heavily upon only the right people knowing, which admittedly in universe is the case, but if it leaked out it would provoke the Inner Sphere powers to join in the fighting against them, if only for "You made the Clans angry, secular ComStar was right! Death to the Fanatics!"
I dunno. What are they going to do, complain that ComStar took in refugees? That would be pretty hard to sell even for the House Lords. They can't even complain that ComStar/WoB hid knowledge of the Clans, since all they have to do is reply with "Well, that was in 2830...who knows how they had changed in 2 centuries. Oh and while we're on the subject, why aren't you complaining about the Dragoons who knew they were coming much better than we did..AND sent back detailed intelligence reports on your nations."
Considering the Jihad wouldn't have happened, I can't see this revelation provoking people to fight against them.
I'm somewhat disappointed with how little the Com Guards, and ComStar in general, were shown during the Jihad. They got pretty much obliterated during the opening moves of the Jihad, which is fine, but there was an opportunity for some really good stories behind the battles between the Com Guard and the WOBM that never really happened from what I have read so far. I guess there are quite a few stories on BattleCorps about Case White which may be more of what I am looking for.
I just would have liked to see more of the Com Guards during the battle for Terra. It was nice to see that the Com Guard commander from the Fall of Terra book was able to survive and wage a guerrilla war though.
Yup, there was quite a bit of potential lost there. Its touched on a bit in Target of Opportunity I believe (a MWDA novel) where they have a ComStar commander fighting against a Blakist unit that's commanded by his wife, but we see very little of that. Not to mention the writers went out of their way to make the WoB so mind numbingly evildumb that you can't write a tragic story with them in it, its just "hah! Kill the evil scum!"
