"Plenty of FO's around the world have sat there and said nothing while the Captain proceeded to kill them.

Anyway, in today's PC world and we all know it, and nothing's done about it...some cultures let face saving, social standing, seniority and rank interfere with training and proper CRM in their flight decks to the extent where pilots will let a situation develope and let it go to it's disasterous conclusion because they're too afraid to speak up.
Unless these cultures can prove otherwise, their airlines are not safe and should be banned from the air space of responsible air transport participating nations.
