Well, the war isn't winnable. If one defines "a win" (and Trump has dementia; he hasn't defined "a win") then whatever "win" equals, it doesn't equal anything militarily realistic for the US.
I'd add Trump's doesn't have guts. He is a cognitively impaired con artist who is frightened half out of his mind that he will be assasinated by Iran.
The irony is Iran never planned to assasinate him until he assassinated Iran's head of state.
He isn't going to finish anything. He doesn't even know what he's trying to do let alone how to do it.
