I think the Unquadnilium bluff worked twice for Kirk.
It's clear Calabra and Treasury are playing hard ball - asking for more shares in exchange for not stealing $20B. Obviously if the NWS is unwound, Treasury owes F&F - so if they set a precedent for exchanging shares for cash, Treasury may have to give back some of the warrants along with crediting F&F.
It will be interesting to see how many shares they think $20B is worth. I'd say we use that same ratio to decide how many warrants they need to cancel for overpayments.
So what happened next with the corbomite ? Did Kirks brilliant poker plan work ?
