when humans have diplomatic interaction with their allies, all talks and speeches are conducted aboard one of our Star Destroyers. A smaller one, to be sure. The diplomatic envoys are received with full honours and treated like the very special guests they are: the Commander himself graciously gives them the use of his own cabin (a baffling tradition… why not just set up separate quarters? still, this custom is meant to honor the guests, so no one complains).
of course the guests are given an entertaining tour of the ship if they have never seen one: weaponry, practice drills, safety systems, mess halls, everything of importance.
the guests are impressed on how ready the human crew is to respond to any emergency, the weaponry is truly amazing, and they are shocked at the ability shown by the X-Wings pilots.
when the talks and negotiations start, humans do everything to make their guests comfortable, providing refreshments and comfortable seats, and they are all in this very nice room situated on the command deck, with a staggering view of the mighty ship… ah, we’re so proud of our Sun Tzu! There’s no other race who can make such a ship! it’s not even one of our best or biggest, you should see the flagship, the HSS (Human SpaceShip) Jedi Star Destroyer…
there’s almost never need for humans to resort to threats, nor anyone dares to formulate them.
