What the "God gap" people want is for the U.S. to take a religious position, of course, and that is, if not impossible, highly dangerous, because what position are they going to suggest the diplomats take? Southern Baptist? Orthodox Jewish? Buddhist? Episcopalian (which group ... the tolerant or the gay-bashers)? There is no end of trouble in this, and the Post is absolutely correct in equating our respectful posture to the fabricated missile gap of 50 years ago.
There is a point to be made beyond the obvious unAmerican-ness of a foreign policy predicated on sectarian metaphysics, however. The point that the zealots want to make is that America is a Judeo-Christian society and culture. The point that should be made is that the American culture is distinctly pluralist and that we respect (in theory and practice ... most of us) the religious rights of everyone. You see, then, that pluralism becomes and intolerable act of faithlessness to the zealots, who will have the whole cake, frosting, and candles or no one will have it.
I frankly trust the U.S. State Department to continue its low level and respectful acknowledgement of other's religious ideas, but I do not trust any part of the federal government to keep the zealots out. The U.S. Air Force (and parts of the U.S. Navy) have been captured by zealous Christian fundamentalists in the past. It is clearly wrong for anyone to use a federal government agency to promote its own religious doctrines ... but it happened and continues. This movement "towards closing the God gap" has to be thwarted, because it is a trojan horse.
