Seriously.\n\nThe Union army was huge at the end of the war. Unlike the attempts during the War of 1812, it truly would have been just "a matter of marching". The Fenian raids, the Alaska purchase, cancellation of the Canadian–American Reciprocity Treaty and the Manifest Destiny doctrine were all contributing factors to Canadian confederation. They certainly weren't the only factors, but they were not insignificant ones.\n\n\nI have always thought Manifest Destiny is one of the most stupid concepts ever concocted. \n\nI would consider the Fenian Raids to be more of an Irish vs British issue, in light of the way England has treated the Irish and Scots. Well, and just about everyone else they encountered and subsequently beat to a pulp.
