The United Republic of North America as being composed of Canada, Mexico, and "the political remnants of the United States," suggesting a dissolution of the Union.[3]
Additionally, in his report on Admiral Preston Cole, Codename: SURGEON makes reference to the Battle of Gettysburg, which he describes as taking place during "the first American Civil War."[4] This wording strongly suggests that there was in fact at least one more civil conflict, which may or may not have resulted in the dissolution of the Union. It is important to note that the word "first" is not capitalized, indicating that it is not the formal name of the war (unlike, for example the First World War). Therefore, if a second civil conflict did take place, it would almost certainly go by a name other than the "Second American Civil War."

At some point, America destroys or destabilizes itself. What remains merges with Canada and Mexico and forms the North American Republic.
Further, its theorized that the UN HQ is located within New York, as the current UN HQ is in New York. UNSC Supreme Command, as its called, is confirmed to be in America somewhere.
