He sees that soldiers are slaves of Nation States in service of Geopolitical goals so he creates a mercenary army free from any country, to fight for whoever regardless of ideology
This just makes soldiers slaves of the market and it's Geopolitical goals :think-mark: and when MSF got rich enough that they didn't have to take every mission, the soldiers just became pawns of Big Boss, Kaz, and Ocelot. Virtually no different than serving the US or the USSR, which they end up doing anyways.
A world where soldiers are free and will always have place? The only person remotely free in this new scenario is Big Boss!!!!! :think-mark:
The thing about Big Boss and Outer Heaven and Mother Base is that the MGS series goes from treating him like a bond villain in the 2D games (Metal Gear 1 & 2) to treating him like an Antihero in the later games. They even erased the swastika off of the original Outer Heaven logo.. Kojima has liberal free market auteur brainworms and it shows in the ideology of his games. He literally developed his understanding of geopolitics from 80s american action movies and says so in interviews.
Phantom Pain, minus the big plot twist, basically does the work of rehabilitating big boss. It also does the work of rehabilitating the NGO-fication of third world governments that were deliberately destabilized by the US. Phantom Pain also seems to ignore Operation Cyclone entirely, and manages to make the soviets seem like an evil empire invading Afghanistan for no reason, while also rehabing the Mujahideen without showing them (except for one guy, Malak, who you rescue in an early mission.) Not a single non-mujahideen Afghan civilian is shown. Only soviet outposts. The socialist government of Taraki that was overthrown by the US/Mujahideen isn't mentioned at all.
Then you've got weird colonialist white savior shit going on with Eli/The White Mamba/Liquid Snake. Am I really to believe that a bunch of African child soldiers in the Angola/Zaire border region answer to an orphaned white boy with a shitty attitude? That entire subplot was just an excuse to shoehorn in characters from the older games.
If Peace Walker-era Kojima had made MGSV, he would've instead been a hot babe who would've become a secondary character on Mother Base and who would talk to you about the history of the Mujahideen (also you could probably see her in her underwear in a dating minigame or something)
