None. A stillborn white dove is a white dove. Ergo the answer, my friend, is it doen’t even have to live.
How long do people have to work for peace before there is peace and they can rest (in peace)?
To quote words misattributed to Plato: Only the dead have seen the end of war.
Those currently alive choose not to see genocide.
History and reason make the answer to this one: The number of seas the dove must sail is greater than the number of seas that exist. It never will rest in the sand.
ALSO: Doves don’t sail.
ALSO: If you’ve seen a release of white doves, either you’re lying (about something so weird to lie about you must be weird) or you were lied to. They were pigeons.
BONUS: Two Abrahamic religions liken YHWH to a dove during creation, hovering over the face of the waters. Flawed, but who could imagine YHWH as a hummingbird?
OH!: Doves do not sleep in sand. They sleep in nests.
