Could the Federation defeat Star Wars' Empire in an all-out war?
Would a Federation warship like the Defiant out gun a Star Wars Star Destroyer? Who has a bigger armada? Who has the tactical advantage? Don't forget that The Federation includes the Klingons, who love warfare and have fast, agile, heavily armed ships, with cloaking devices, and the Vulcans with superior logic and tactical planning.
The only convincing question I have seen is "both have shields, but the Federation has teleporters. Can Star Wars shields block teleporting a torpedo onboard?"
I still think the Empire fleet outnumber Federation torpedoes, but it's a good question.
