There are a few passages in there that in isolation are not very notable, but taken together are kind of interesting:
>But countries do not go to war simply to have a war – well, stupid fascist countries do, which is part of why they tend to be quite bad at war – they go to war to achieve specific goals and end-states.
>Again, it is not a ‘gain’ in war simply to bloody your enemy: you are supposed to achieve something in doing so.
There are a few other passages to similar effect, but for brevity, these two will do to illustrate the point: the author seems to be subtly implying that America is a "stupid fascist nation". Actually, the way he keeps clarifying the obvious, I think he expects a good amount of his readers to be "stupid fascists".
I cannot say I wholly disagree with his assessment!
> the author seems to be subtly implying that America is a "stupid fascist nation"
He does nothing of the sort.
I can clarify for you: the mention of fascist countries being bad at war is a link to another article by the author, which explains that fascist countries such as Mussolini's Italy and Nazi Germany were very bad at a war even while they mythologized and romanticized it, and derived their "sense of nation" out of symbolic struggle and might. The article you linked to describes many fascist or fascist-like nations, like Putin's Russia, but does not mention liberal democracies such as the USA.
I recommend you read it.
So why did the author mention that article in this context? Because he wanted to explain that countries -- unless they are fascist countries -- have strategic goals for going to war, and so does the US in this case, and therefore it's warranted to look into those goals and whether they have a chance of being met.
Again, I recommend you read the article in question (the one about fascists being bad at war) before jumping to unwarranted conclusions.
