There are many ways to reconcile the "too advanced" look in the context of the game.
For starters, the whole idea an earlier, "more advanced" and unheard of design, was the point, hence the name.
Then, it really wasn't supposed to work
it needed actual magic to work.
And to finish, it's not really a better weapon than most of the Metal Gears, it's only really nuclear if it self destructs, I would assume most countries would rather have a Rex or a Peace Walker (which can even fake nuclear threats), than a Sally.
