He didn’t endure any torture in Vietnam , that is a myth he has spread.
It’s part of the reason that Nam Vets and those very close to then (such as President Trump) hate MCCain for his self serving lies
McCain is a lousy politician, but he wasn’t a coward or a traitor while a POW. He ejected from his crippled A-4 and sustained multiple and severe injuries to his body that were not properly treated by the North Vietnamese. I am a former Navy fighter pilot, and I have a good bit more insight into McCain’s military service than most on this forum. The inhumane treatment and torture of the POWs caused almost all of them to break. The Code of Conduct no longer requires you give only name, rank, service, and social security number. You resist as long as possible, and then give as little as possible, hopefully misleading or worthless information. You then tell your POW chain of command what occurred, if able. Probably not going to convince you, but my own training made me realize the limits of human endurance, even under controlled conditions. Please stop with these misrepresentations.
