It might, but I think the US military is a great tool and does its actual job fantastically well. The only thing you can really blame them for is that they did not give a broad enough set of strategic options to civilians.
That said the civilian government usually gives them nonsensical task that they simply can not do.
Oh for sure. But relatively to other military they are quite good and even while they waste a lot they can mostly to their jobs. Other military are very expensive and very ineffective.
It's just that USA military never seem to win any wars... or honorably escape from any conflict... or actually accomplish anything they ever claimed to have set out to do. Even if we're generous and put Korea in the win column, that was a really long time ago.
Again, the win the traditional military conflict and that is their primary responsibility. They are not equipped to do Nation building and they don't have the political support to do it. That's why they never exit a conflict very well, but they always crush in the beginning.
Korea was the last time they had a real problem winning the traditional military conflict.
"In the beginning" is when there are no reporters or other observers on the ground, so we have to just take the military's word on everything. If we just asked the Cleveland Browns how they did last season, they might tell us they played pretty well.
Besides, is it supposed to be hard to use billion-dollar stealth weapons to kill a few malnourished soldiers equipped with 1960s-era Soviet surplus? The worst part about the upcoming war with Russia that we're determined to have might be that we're going to get our asses kicked, from the beginning. Expect to see more airports completely operational within hours of multi-million-dollar missile attacks.
That said the civilian government usually gives them nonsensical task that they simply can not do.
