So I'm wondering what Fujitora's last line means. Is he actually going to try and get "Strawhat's" head? Or is he saying he'd be willing to be an admiral without a single base that would accept him? I'm guessing the latter. He won't resign from the service, but he will essentially be a "rogue admiral" in that he will maintain his title, but not get any assistance from the Marines/Navy from the outside except for the loyal men under his direct command.
This also suggests an informal alliance between Smoker and Fujitora as this chapter solidifies that they are both out for the same goals. This in turn could end up leading to a schism within the WG ranks, as in more marines or officers aware of the current WG hypocrisies and becoming more sympathetic to Fujitora after this event. Smoker did not have much pull to achieve such a thing, but Fujitora might. Maybe not outright traitorous actions, but quiet support of Fujitora.
From here on out, it seems that Fujitora & Smoker have since resigned themselves to keeping more of a more laissez-faire attitude toward the Strawhats in the long run–that is excepting instances where they directly attack the WG. We will likely see this play out in future entanglements.
As for Kuzan, I think he's mainly intending to keep an eye on Blackbeard and find out exactly what he's planning and "joining" him is the best way to do it. Also, Blackbeard is technically a warlord so the WG is essentially letting him do almost anything he wants.
And the Kid alliance vs Shanks....not hard to see which one comes on top.
@SuburbanErrorist:
Fujitora basically gambled with lives. If he had to resort to that to achieve his goals, then so be hit. It's a gamble.
He did however help people when running and when pica was destroyed he'd stop the rubble.
He's a gambler. He made that sacrifice of having people killed.
Why do people expect an absolute protection of everyone?
Yes, this chapter solidified Fujitora as the "gambler" not only in games of chance but in achieving his goals as well. Also this alludes to Alabasta in the same sense–that the marines were "powerless" (not in merely physical sense but also a political one) especially since it is more clear here that Doflamingo's appointment came directly from the CDs. The big exception here is that Fujitora already knew that the Strawhats were useful agents for the "greater good" in taking out rogue Warlords and their ilk like Ceasar Clown.
