Guys, this is getting to be a bit of a derail, the more so since the Successor States
already have known that ComStar has it's own agenda that is not the same as theirs. See
what happened at the start of the Second Succession War. (Plus Comstar has done the Steiners and Kuritas dirty in canon). It's a bit more suited for a general Battletech thread than this particular story which has a very different focus than ComStar shenanigans.
All this information will be doing is to give further proof to the Lyrans that ComStar is involved with the technological decline of the Inner Sphere. (and to the Mariks that ComStar was involved with Anton's Rebellion)
Unfortunately, they can't easily get rid of the Blakists (although all of the Great Houses both want to and have secret contigincy plans to harm ComStar/infiltrate ComStar along with additional plans marked 'what to do in case of Interdict'.
