The whole parking your fleet to start wars mechanic seems odd to me anyway.
If you're really playing as the minister of the navy, deciding who your nation goes to war with should be outside of your control and up to the cabinet. If Churchill had parked the Royal Navy outside the US East Coast in 1914 to create tensions with the US he obviously would have been promptly called off.
I like the events in which you can give your input to diplomatic decisions but just being able to go to war with whoever seems very gamey for what the game is otherwise going for.
