Wow, that was a really interesting article on a topic I know nothing about. Thanks!
The Wikipedia article is accurate, based on what I know and see of dispensationalism. It is the majority belief in American evangelicalism.*
Left Behind,
Late Great Planet Earth, all that stuff. Even if any given individual isn't up on all the details, it's the "air they breathe", the categories that they think in.
It's a common belief, among those I've interacted with, that we dare not do anything against the interests of the modern state of Israel, especially with respect to their occupying territory. To go against the modern state of Israel is to call down God's curse against this nation. And, it's a huge voting block that believes this.
Just for grins, contemplate this: Those popular pundits I hear, think (based on a quirky read of Isaiah 17, an oracle against Damascus) the next thing up on the "prophetic calendar" is that Israel lobs a nuke on Damascus. And I truly believe that some of these guys would be cheering wildly on the sidelines if something like this does happen.
Bad eschatology has consequences.
*not, I hope it's clear, a belief I share. I've ranted on this elsewhere.
