I had this idea about Tom Riddle's plan that I appreciated having criticized.

Tom Riddle grew up in the shadow of WWII. He saw much of the Muggle world unite against a threat they all called evil, and he saw Europe's savior, the US, eventually treated as the new world leader afterward, though it was somewhat contested, of course. That threat strongly defined it's own presentation and style, and so that style and presentation were associated with evil afterward.

Tom didn't want to be Hitler. Tom wanted to actually win and to rule in the longer term, not just until people got tired of his shit and went all Guy Fawks on his ass. He knew that life isn't easy for great rules, but thought that was worthwhile. He knew that life was even harder for great rulers who ruled by fear, so that wasn't his plan.

So Tom needed two sides, good and evil. To this end he needed two identities, a hero and a villain.

I guess he didn't think the villain didn't need to have any kind of history. Maybe he didn't think the villain would matter much or for long. Voldemort was just there for the hero to strike down. That was a mistake, because he lacked a decoy his enemies were eventually able to discover his identity.

Then there's this hero. The hero is a what passes for a minor noble in magical Britain. He's from a 'cadet' branch of the family, which means he doesn't stand to inherit anything substantial because he's not main line.

Most importantly, he goes missing in Albania. That's a shout out to canon and a code phrase for "became Tom RIddle's bitch."

As Voldemort, Tom sows terror and reaps fear. He's ridiculously evil and for Dumbledore redefines evil because he is apparently evil without necessity. Dumbledore can't tell what function that outrageous evil serves because Dumbledore thinks that evil is done sincerely. He doesn't know it's just a show.

Tom stages a dramatic entrance into the drama for his hero: he saves the president's daughter, or something like that. Totally Horatio Alger. It's a cliche, which may be EY's way of helping us to understand that Tom is fallible, more then than now.

Tom promotes his hero from Minor Noble to Last Scion of House X by killing off the rest of his hero's family. Tom simultaneously builds legitimacy for his hero's authority and leverages the tragedy to build sympathy for his hero's cause.

Tom's mistake was thinking that would be enough. There was a threat to the peace. There was a solution. The people instead chose to wallow in their failure and doom. He made it all so clear, so simple, and yet the morons just didn't get it.

I'm sure anyone whose been the biggest ego in the room during improv could sympathize.

When Tom realizes that his plan has failed and cannot be made to work in the intended fashion, he exits his hero, stage left. At that point, 75 or so, he doesn't have a good plan to leave the stage as his villain, so he kind of kicks it for a few years, tolerating the limits of his rule and getting what meager entertainment he can out of being a god damned theater antagonist.

When Tom gets a chance, he pulls his villain off the stage and may or may not have done something to the infant Harry Potter.

Now he's using the Scion of X as an identity layer to keep the fuzz off his back, while manipulating Harry into a position of power, and I'm guessing he plans to hit Harry with the Albanian Shuffle a little while later and give World Domination another try.

Tom Riddle is a young immortal. He makes mistakes but has learned an awful lot. He is trying to plan for the long term and has nothing but time, and so can be patient.
