I think part of the reason that many Americans have the mindset they do is because the US thrived after WW2 by not having any large scale infrastructure damage. War torn areas force people to become more caring and work together. Being isolated and never having directly experienced war caused a reinforcement of exceptionalism and individualism. I think a war on its soil would do a large amount to change peoples mindsets.
Edit: just a reminder unpopular opinions should be upvoted.
Really? I thought we dispelled that myth in the 1960s with Vietnam. We then dispelled the myth of the USA’s ability to execute ‘nation building’ with Afghanistan and Iraq war 2.0.
