Aside from divine intervention on the part of the Prophets, what made Starfleet decide Ben Sisko was the best choice for the difficult mission to Bajor? He doesn't appear to have any experience in diplomacy. As far as I know, he was a starship bridge officer, and then went into designing weapons and ships after Wolf 359. The Bajor posting required someone who could balance the vying factions and rebuild a world shattered by decades of occupation, oppression, malnutrition and barbarism, and prepare them for Federation membership. It also needed someone capable of handling the Cardassians. Now obviously in retrospect they made the right choice. But if the wormhole had been known prior to his appointment, would a more senior, more experienced officer have been assigned instead? Was Sisko given a helping hand by a friend at Starfleet Command?
