Possibly. Don't know if getting into a new x-pack, possibly with bugs and whatnot, is a good idea, so probably not.
Tried invading Sweden without first joining the Allies, it's working like a charm so far :3. Have taken a coastal city by landing a division from the sea, and I've also captured that strategic resource (forgot what it was, supposed to be doing schoolwork right now :P ) in the north, and I've got a third division storming towards Stockholm as we speak
. We mobilized before declaring war, so we invaded with a full-strength army, whereas Sweden had reserves that have proven no match for us so far. The country will be ours before long
