The U.S.-trained engineer who rode some improbable twists and turns in Egypt's 16-month transition to democracy is an enigma: Despite his education, he sometimes struggles to communicate in public and can be off-putting to some secular elites.

The bespectacled and bearded Morsi squeaked to victory in the freest election in Egypt's history, and now the 60-year-old university professor must prove his mettle by standing up to the ruling generals who in recent days have stripped the presidency of real power.

For 35 years, Morsi obediently followed the Muslim Brotherhood's strict rules, abiding by the principle of unquestioned obedience to its supreme leader — a position that changed hands five times during that period and currently is held by Mohammed Badei.

Morsi has dutifully mirrored the group's strategy of couching a hardline doctrine with short-term pragmatism. In an example that looms large now that he has been elected, Morsi is anti-Israel but he does not call for annulling Egypt's 1979 peace treaty.
