HAPPY DAYS WERE HERE AGAIN

It's interesting to note, in these days of political realignment, that—per the subtitle—Buckley now seems to be calling himself a ``libertarian'' rather than a ``conservative''- -though you wouldn't know it from the almost invariably middle-of- the-road to left-leaning targets he spits darts at in this generous collection of National Review columns (1985-93), speeches, and essays from Playboy, The New York Times, and elsewhere. First up is a 1985 column on Carl Sagan, knocked here for letting his fear of nuclear winter overwhelm any fear of Soviet domination—though within Buckley's acerbic critique lies, as usual, a saving grace of humor: ``Carl Sagan gave a half hour's performance [before a Congressional committee] so arrogant he might have been confused with, well, me.'' Last up is a 1985 tribute to Ronald Reagan (``As an individual you incarnate American ideals at many levels''). In between, in pieces arranged thematically rather than chronologically, Buckley mostly targets, but sometimes trumpets, student protestors, Idi Amin, female would-be combat soldiers, fundamentalists, Bush (``His Supreme Preppiness''), Gorbachev, Castro, the Sandinistas, Charles and Diana, Dinesh D'Souza, and nearly every other high-profile political and moral icon or straw man of the era. It's a bravura performance, albeit one indelibly marked by Buckley's perpetually righteous, and right-wing, stance.
