I mean the lack of clear goals in American wars just reinforces their point

Nope. An ability to set and accomplish sensible war goals and an ability to overpower enemy's armed forces are not the same thing at all. As US has demonstrated repeatedly.

A fleet of AI-controlled F-16s? That contributes to the latter.

A lack of clear goals is a symptom of bigger, organizational issues is what I’m reading. The problem isn’t as much raw firepower as it is strategy and execution.

Clearly, the technical solution to that is to remove the command over US armed forces from the US president, and hand it over to something more sensible - more capable of setting and executing military strategy. Like Skynet.
