Spain DoW'ed me (Russia). This war will not be fought in Europe, but in Northern-America, where Spain and I have many colonies and cities. Most of my cities there have no fortresses.
How useful is it to start building (or expanding) fortresses in those cities at the start of this war ? When Spain cannot capture them within a year, before the fortresses are finished, it is OK to me. But when Spain captures a province before the fortress is finished, what happens then ? Will they get "my" fortress for free ? Do I have to recapture that province by seiging my own fortress ?
