We consider a realistic example of supersymmetric grand unification based on SU(3){sub {ital c}}{times}SU(3){sub {ital L}}{times}SU(3){sub {ital R}} in which the electroweak (EW) Higgs doublets are {open_quote}{open_quote}light{close_quote}{close_quote} as a consequence of the {open_quote}{open_quote}pseudo Goldstone{close_quote}{close_quote} mechanism. We discuss radiative EW breaking in this model, exploring in particular the {open_quote}{open_quote}small{close_quote}{close_quote} (order unity) and {open_quote}{open_quote}large{close_quote}{close_quote} ({approx_equal}{ital m}{sub {ital t}}/{ital m}{sub {ital b}}) tan{beta} regions by studying the variations of {ital r}{sup 2}({equivalent_to}{mu}{sub 1,2}{sup 2}/{mu}{sup 2}{sub 3}), where {mu}{sub 1,2,3}{sup 2} are the well-known MSSM parameters evaluated at the GUT scale. For {vert_bar}{ital r}{vert_bar} sufficiently close to unity the quantity tan{beta} can be of order unity, but the converse is not always true. {copyright} {ital 1996 The American Physical Society.}
