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.
The tactical blunders resulting in the loss of noncombatant life are only so widespread because of the civilian leadership's priorities. It's rarely the fault of any one servicemember.
