People who get captured aren’t losers. John McCain spent 5-1/2 years in a notorious North Vietnamese camp, 2 of those years in solitary confinement. He refused to take an early release because he knew it would mean people captured earlier would be held longer.
He also felt that the North Vietnamese would use it for propaganda because he was made that offer based upon the rank of his admiral father. I may not have agreed with some of his politics, but that doesn’t mean I don’t consider him a hero.
