So, what I'm reading from this is outright revolt by the Peacock faction--or the most militant parts of it--followed by them being too toxic to associate with, and/or being too brutally suppressed and deciding to submit. (Since most of the ruling class is Peacock, I don't see any other way that they simply stop.) The latter outcome, of course, is bad for our internal stability in the long-term.
And this is assuming that the Peacocks don't just outright win the conflict. They are the majority of the ruling class.
I prefer to let uncaring resignation slowly destabilize and defeat them: it keeps our schedule intact. We have so many megaprojects on our todo list that avoiding the Peacocks for 18 years isn't all that big a deal (and there's only 1.8 expected Influence loss during those years).
I don't want to wait 18 years before building warships.
