"It's a dead letter,"

That phrase doesn't mean what you think it does.

There has never been and will never be a Supreme Court opinion issued on the validity of the War Powers Act. Any case on the subject would present a non-justiciable political question. The only law on the subject emerges from the course of dealing between Congress and the President. Presidents deny that the War Powers Act is valid and Congress won't take any steps to enforce it. That's where the matter ends. The law in question isn't valid. It is a dead letter.

Yes some future Congress could, in theory, try to revive it. France could restore the Bourbon monarchy and Russia could bring back the Romanovs, but it isn't going to happen. Unless you want to be a laughingstock on a par with French and Russian monarchists, it's time to give up this weird obsession with the War Powers Act. To be blunt, you have no idea what you are talking about.
