All of these advanced death machines need equally advanced supply lines and staging grounds, both of which would run through civilian populations. Look at Afghanistan as an example: with all the might of its war machine the US couldn’t kick the Taliban out, who we love to tout as fighting with sticks and stones.

In fact the only issue stopping a worker’s revolution in the US is the lack of organization. The technology factor is really small in comparison to the inherent asymmetry of the situation.
