So far, the US has done fair with a representative democracy, though the current regime is testing that to its limits and then some. But the US has always had a Judeo-Christian ethic, even if distorted. It has always had an idea of a God whose primary desire is to bless. Once you get a “God” who either doesn’t care or is heavily into damning, the political needs change.
The challenge for us is how to attempt to bless a society that isn’t ready to accept many blessings.

With what I know, and I'm sure that isn't much, I would destroy all of their ability to fund war. I really would. When ISIS takes an area, I would destroy the oil facilities and wells in that area.
