Regarding the nuclear/nucular problem:

There are many words in English that end with -ular and only a few with -lear, and there is only one other (that I can find on my CD-ROM American Heritage Dictionary) where -lear is pronounced as two syllables: cochlear, adj. Pertaining to the cochlea, an inner-ear organ.

A few of the more common ones: angular, cellular, circular, consular, curricular, granular, insular, jocular, jugular, ocular, particular, perpendicular, popular, regular, secular, singular, spectacular, vascular, ventricular. (And then there are the words that can be built up from these: triangular, multicellular, etc.)

So if you can't forgive "nucular" at least you ought to be able to understand it.

I predict "nucular"--at least the pronunciation--will become more accepted and will be added to dictionaries in the future.
