What if, for whatever reason, all of Spain's colonies in the new world failed? Who would colonize where? What would the end result be?
Sorry for the simplistic WI, I was originally have all the major empires (England, France, Portugal, and Spain) have their colonies in the New World screwed over, but if that happened, I think everyone else would decide the new world was hopeless and just not bother with colonizing it at all, which would be great for the natives, but not what I'm looking for in this particular alternate history scenario.
