To see the Soviet Union rise back to power from the ashes is a wonderful thing. Your nation could bring many good things to the Nation-Wars world, but let me be clear on one thing, Spy missions against out country resulting in sunk ships and military casualties will not be tolerated.
Currently the USSR has a couple of options, it can accept retaliation for the attacks it has already made and we can move forward with the peace process or you can continue down this path and find your nation in a full blown war which clearly will not be good for your nation.
You choose!
