I don’t necessarily disagree with your take here, but this is all conjecture until we see a 5th-gen in real combat. There was that story about an Israeli F-35 sneaking right up to a… I forget what, Syrian AF probably, but even if that anecdote really happened we haven’t really seen them used in anger. As I said elsewhere here, China is really the only one who’d offer a near-peer opponent (unless god forbid the US go so far off the rails that they turn on NATO).
