All of this for a dude being, at worst, unable to read his messages for a day or so.
I don't mean to metagame and all, but infil attacks have only been used as justifications, not as dissuasion (at least, not successfully on other continents than the Colonies, and perhaps even there).
BoM just lost their General to a infil. We were probably lucky that we were refitting and not in the middle of raiding.
