No, Dave, you're not missing anything. The religious right has pushed its futurist view of eschatology into the political arena, and attached it to American policy toward Israel, as well as having developed a view of America as the chosen protector of the chosen people in much the same way that Anglo-Israelism developed in Great Britain during the Victorian period. There' this idea that somehow, the superiority of the English speaking peoples puts God in the position of holding our coat-tails and cheering us on as we assume the mantle of the Old Testament covenant relationship because we hover over the "Israel" that exists today. Aside from the major difference that the Israel of today is not even close to the homogenous Jewish state that it was under the OT covenant, that its government is a completely secular, largely atheistic entity representing a predominantly atheistic and agnostic population that includes a large minority of Arabic speaking Muslims, somehow, through futurist eschatology, the thinking is that this will somehow bring some kind of revival or covenant relationship between God and Washington, DC. At least, as long as the Republicans are in charge.
There's an eerie echo in this that goes back into Mitt Romney's Mormonism. Mormon theology denies virtually every core tenet of the Christian faith, from the virgin birth, to Jesus' divine and human nature, to the resurrection, to salvation by grace through faith, to the atonement. It is as close to the New Testament definition of Anti-Christ as we have existing in the modern world, and it is a great deceiver, hiding behind good works and good deeds. One of the core doctrines of Mormon prophecy is the prediction, by Joseph Smith, that the Mormon church was being equipped and prepared to assume the mantle of political leadership of the United States, and, once in their hands, they would use the political, economic and military might of the US to conquer the rest of the world which would usher in the Kingdom of God on earth. Somewhere in their end-times litany, the God of this earth, who is really Adam, the first man, and Jesus, who is his flesh and bone son produced by having sex with Mary, hand the mantle of godhood over to Joseph Smith, who then becomes the "god" of this world. From a conservative, evangelical perspective, that is blasphemy that deserves the 'anathema" of Galatians 1:8-9, yet there are conservative, evangelical leaders who will bust a gut trying to get this man elected President of the United States. Maybe the apocalypse is just around the corner!
