I'm not quite going to be too aggressive yet, although I think I'm gonna be involved in [@Willy Vereb]'s European wars (and probably come out of them badly, so as to give my nation some glory days to harken back to).

Perhaps leaving some turf in North America blank but at least inhabited would give those nations something to squabble over without being too directly aggressive toward each other? I don't think I can quite process enough territory to take anything else on just yet.
