You misunderstood my definition of P.

P is *not* the well-ordering theorem, but the proposition that the WOT is
provable in ZFC.

So, in effect, your answser is that P *itself* ` has been, and will be true'.
In other words, here we have a mathematical proposition on which both of us
agree that it is eternally true.
