I suggest avoiding conflict with the water nations unless you have the ability to pursue them into the water. Otherwise you will have to defend yourself from endless attacks from the sea.

Frankly, if they go to war with you before you are ready, your situation is bad.

There is nothing "technical" about it. If they declared then you are at war. They are your first things to deal with, since they will attack you with armies if you and they share any borders.
