A few interesting possible outcomes:
1) The SEAL community officially collaborates his claims: O'Neill is vaunted as one of the most important "operators" in US History. Haters are forced to eat their words as the man that shot and killed OBL (by himself and without help) begins a new phase in his campaign of personal glory for profit. Tim Kennedy and that Schreck-Dude each file defamation suits against the entire internet for a jillion dollars. Countless 'Bro-Vet' content creators that rely on monetized "this guy is a fraud" social media videos to pay for their craft beer and Copenhagen are forced into hiding and transition from "poser busters" to making EweToob videos of "top 10 life hacks" that show people how to make a dog food scoop from an old milk jug, or a "chip clip" from an old clothes pin.
2) The SEAL community (some of whom already seem to have suggested that O'Neill is embellishing his story) debunks his claims as embellished. The bro-vet community implodes. The 'Fraud Police' are emboldened, energized, and filled with "I told you so" self righteousness. The "poser buster community" begins to systematically tear apart every war story ever told. Angry former E7 SOF Operators & "Content Creators" that love nothing more than accusing anyone above their/them/they/xe/xem/xir former paygrade of being a fraud begin posting new content that claims that their/them/they/xe/xem/xir has "proof" that the wartime exploits of Napoleon, Genghis Khan, George Washington, Sun Tzu, and the Skipper of the Maersk Alabama may or may not have embellished some obscure detail of the exploits that made them all famous...
...they/them/their/xe/xem/xir claim full vindication that by outing O'Niell, .they/them/their/xe/xem/xir are now duty bound to out, EVERYONE
3) The entire SEAL community closes ranks and refuses to comment one way or the other - essentially "covering" for O'Neills version of the story with the time honored "we can neither confirm nor deny the facts surrounding this highly classified mission" and we are all forced to live in agony as we all hunger for the truth about...
...seriously, does anyone really give two shits about this kind of social media high school drama anymore?
