I think you missed my point, which is that in the US, people typically described as nationalists tend to be pseudo-nationalists who value pomp and ceremony, but not substantial concrete actions to better their country or actual real care and love for their fellow countrymen. In terms of percentage of the population who value and love their national identity, we are no different than anywhere else.
See https://www.pewresearch.org/global/2026/02/17/what-makes-peo... and especially note that the US is one of the top countries for percentage of population with primarily negative views of their country, at 20%.
