Really, i believe there is no interest to provoke the european powers, even in a "preventive" strategy.
First reason, the french and especially british navies are far more powerfull than Union navy, except if the union player uses the main part of his means in the reinforcement of deep water fleet, means that are more usefull in building ground forces in my opinion. No doubt that the union navy cannot compete with the allied fleet most of the time.
Second reason, a preventive attack over London or Paris will logically involve the war declaration of allies against USA and unlock the forces in Canada, London and Mexico, wich is never good news for Union player ! Particularly with the 1.14 patch wich increases the number of available division for CSA from 30 to 40. Added to the 2 french divisions and the 10 british divisions, it means that the Union player has no more numerical superiority to expect till the end of the game.
But if you want to do it Phamtom, i will be pleased to welcome the red coats and the foreign legion by my side
