Leadership ain't just about making the country strongest my dude.
Yourself admitted leaders are absolute shithole
"Under Sakazuki's leadership"
As in after Akainu became fleet admiral
"Navy HQ has grown far more power and determined"
The marines are now stronger and more consolidated
"Than ever before"
Sakazuki's leadership led to the best version of the marines ever, a force that counters the evils of piracy
Most marines are in tune with absolute justice
What better leader for the marines than Akainu, someone who means business and wants to eradicate piracy
You're acting like the navy is solely made of little bitches like Coby with no real understanding of the politics involved in upholding a force as grand as the navy. Akainu takes no smack from both pirates and the world government.
