The scenario (of which you are all familiar):
Your civ explores a system and claims it.
Upon exiting via another (unexplored) warp point - your ship detects an alien vessel clear across the system at a warp point.
You back out or exit through another unexplored warp point.
You establish a trade treaty with the aliens.
Meanwhile your explorer ship comes back into sector whence it discovered the aliens in the first place - heading for a planet to refuel.
Message: you have left us no choice ... And the war is on! Chrissake! Wazzup widdat!?
