The U.S. Military is universally good for society & humanity.

That said the civilian government usually gives them nonsensical task that they simply can not do.
Korea was the last time they had a real problem winning the traditional military conflict.
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.
There is not gone be a war with Russia. If there was a war you can be damn sure that the US would whip Russia armed forces of the map. Also, Russia official defense doctrine is nuclear response to a lost in conventional conflict.
Again, yes the military is expensive. They do a good job of fighting traditional military conflict. The reason the US never wins is because of defunct politics, not defunct military. The military is just bloated and expensive, but not defunct.
