I read there was actually significant war exhaustion among the public towards the end, contrary to the patriotism lens this time in history is frequently shown with. There was also a lot of effort to censor what was actually happening in the war from the public, both in terms of press coverage and in screening soldier letters to home. I'm not sure how long the american war machine can actually last. All the post WWII wars are characterized by significant public war exhaustion. And these days you are going to have the other side posting on social media POV videos of american soldiers getting decimated by drones.
