America is facing twin challenges – one from within and one from without.

The external challenge is from radical Islam, whose rebirth in the last 28 years has plunged the world into a renewal of the conflict that has defined history for the last 1,300 years.

The internal challenge, just as serious and perhaps even more so, is a clash of worldviews in which the Christian culture that shaped American history is under siege from ultra-secularism, multiculturalism and moral relativism. Add to that an invasion of unprecedented scale from the south, as well as an upcoming presidential and congressional election that threatens to bring with it nothing short of a revolution in the American political landscape.

The big question: Is America doomed, with no way to reverse course? Or can America emerge triumphant, again, as it has so often throughout its history?

These will be the themes of the "Taking America Back" conference Jan. 5, 2008 .
