Alright first things first: the grammar needs a lot of work. It's not the worst I've ever read, but it's pretty obvious you're not a native English speaker, and it got worse as the article went on. Normally I would go through one of these sentence by sentence and suggest corrections, but that would take too long. There's also a few points where I just wasn't sure what you were trying to say. I would advise trying out something like Grammarly to help with that. I've never used it, but I've heard good things, and there's a free version.
The actual anomaly feels like some generic zombie stuff, though I did like the imagery of zombies trying to sing the National Anthem. But overall, the biggest problem with this article is how little it does. At the moment, you just have patri-rotting zombies, and a reference to the real-life My Lai massacre which ends up feeling a bit tasteless since you don't really do anything with it so it just feels like an afterthought.
The description you give makes it sound like you want some big historical epic that draws from real world history and delves into the Authority getting involved in Vietnam, while also being a criticism of jingoism or American nationalism or whatever you want to call it. Maybe that's not actually what you were going for, but that's the impression I got. I'm not saying making that into an interesting article is impossible, but by your own admission, you don't think you have enough content to go forward, and that's a big problem for something like this. The way you describe it sounds like it's pretty ambitious, and you don't even have the best grasp of writing in English yet. I think that you're trying to run before you can crawl, and it would be in your best interest to try something a bit more small scale and then come back to this when you get more confident in your writing ability. When you do, I'll be glad to have a look at what you come up with.
