J. Edgar Hoover used the preeminent evangelical publishing wing, Christianity Today founded by Billy Graham himself and supported by oil baron J. Howard Pew, to publish anti-communist screeds less than 5 years into its lifespan. In it, he argued Christians should support Israel because of "Judeo-Christian values." Hoover wasn't an evangelical, but knew he could bend it to his own ends. Modern evangelical shit was created and/or co-opted by the imperial core to serve it's purposes nearly 100 years ago. We shouldn't even make a distinction between white christian nationalism and evangelicalism, because it's the same thing.
