Christian Fascism is defined by almost complete lack of theology or scholarship, and for being extremely schismatic to a farcical degree. It's a religion of the id, of the pure libido of the American white suburban aggrieved peitit boug psychopath. It's all about petty greed and spite and personal wish fulfillment.

My hypothesis is that they're afraid of the future and afraid of their own mortality and if they can create the biblical apocalypse then they get to side-step both of those issues by getting teleported directly to heaven in the rapture.

It also runs completely counter to the stated goal of their religion

The bible is pretty clear that the end time is unknowable and until then humans have to be good stewards of the planet. Trying to bring about the apocalypse isn't exactly good stewardship

milennarianism requires the twinge of new developments to get the ball rolling, but once it starts 'you can't expect god to do all the work' and 'we need to prepare' apocalyptic ideology start mixing together & spawning actual activist tendencies. this is where you get people selling all their belongings, long distance pilgrimage/migration, novel social organization, and for people with state power, an exercise of it (usually on vulnerable people).

so in this case evangelicals haven't been constantly on an israel apocalypse fever for the 200 or so years whereever you wana peg 'evangelicalism', but it springs from the simple existence of israel which checks one of the prophetic boxes in their interpretation, and then right now they're having a war & spiked the interest because they think there's a bigger opportunity. a couple years ago in the slow apartheid stage of the conflict, evangelicals didn't have the same excitement. unless Lindsey Graham was banging a proliferation drum for the past decade, his statement demonstrates this.

There is a specific passage in, I believe the post-gospel books of the New Testament (but it could be in the gospels but I'm pretty sure it's in Acts or the Letters) it specifically says "you can't predict the time of the return of the Messiah, it might be tomorrow, it might be in a hundred years. YOU WILL NOT KNOW so you must live by Jesus's teachings right now and always not just in the moments leading up to his return. You aren't going to min/max the apocalypse, yo."

Of course evangelicals don't give a shit about this. Doesn't stop them from trying to force God's hand or whatever. Fucking goons. The rapture isn't even in the fucking Bible, either.

I think they're trying to usher in the apocalypse in order to validate their own fucked up worldview.
