Deuteronomy 34:5 "And Moses the servant of the LORD died there in Moab, as the LORD had said."
God does not reign over the dead, but the living. The only important borders are between Heaven, Earth and Hell. In the same way Moses is not dead, He also crossed over into the promised land.
Precisely why I believe the preservation of "man-made" sovereignty of America, Israel and Britain are the only means whereby Judeo-Christian civilization makes it possible to promote goodness in the world. Whereas, without the US (say, it were suddenly wiped-out by a meteorite), the world world would immediately descend into chaos.
I believe this outlook reflects our God-given mission. Our reason for being as a nation.
