The one thing Asimov gives Orwell credit for is predicting that there would be three separate great powers? Like, what? The other nations don't matter at all. We're not even sure they really exist or not. Or how he complains that Orwell used a missile strike, instead of calling it what, a 2X00 Plasma Fueled Missile Strike? It's not about the missile strike. It's about the fear the missile strike incites into people. People afraid are easy to control.
Or about how the warring nations didn't use nukes. Like, there's no way Asimov didn't understand that it was probably not even the other nations that were responsible, but rather the party itself, right? But that's what it sounds like. It reminds me of how in the Foundation series, one of the characters has an "atomic" wristwatch. Like, you can tell that Asimov thought that would be possible in the future and would be cool, and just had to include it. But really, who cares. As if cool gadgets or what people might use in the future is what makes or breaks science fiction. Not to mention how outdated an atomic watch feels now.
Asimov had great ideas, but his actual writing ability doesn't hold a candle to George Orwell's. Orwell was a true literary master. Asimov was a very creative scientist, with a lot of ideas in his head, and he successfully put them to paper.
