Here we good a good solution, keep the game historical.
1) For whatever reason, a Destroyer strength 5 will appear in port. Fact. Guessing it was programmed based on history.
2) When it comes "deployment" time. Allow Italy a choice. Pop-Up says, "Destroyer name <fill-in-blank>" is now supporting East Africa
3) User can choose the following: a) Would you like this ship to sail (appear in port)? b) Would you like the ship to be patrolling Indian Ocean? (if so, ship will appear away from ambush).
One could also, argue, when a neutral is invaded, the defender can configure the defense. Historical people may not like this. But when it comes to Poland, Yugo, Russia, Low Countries, we know the default setup. Neutrals may have at least made an adjustment.
