It seems a lot of folks beat me to this, though I confess it came to my mind the second I saw the Obama “O” salute. The Obama salute appears in the Star Trek episode The Way to Eden. I suppose National Review is Herbert.
Update: A couple of leftwing emailers are claiming the whole salute thing is a joke. Maybe that’ll turn out to be true. But, these folks might ponder why the “joke” seems so completely and utterly plausible.
