KNF refuses to pull out of the Taus when given an ultimatum by the GRN.
KNF loses everything.
That's it really. Can't wiggle your way out of that one unless you have some chats with the developers.
Edit: actually, let me put some context into your statements.
18 years ago, with 100% of the KNF in the core, they still couldn't secure Hokkaido.
Now with 30%, they can?
You say 65% remaining in the core in 4.86 as if that would make Kusari even more impenetrable than it already is, when that's possibly the furthest thing from the truth.
It really seems that the people at the top have started believing in their own myth.
