The Future of Federalism?

So the question for my class this week is what do I think the future of Federalism looks like for America? I think that is an interesting question given that over the last decade the world has seen several federal republics fall apart. One reason for this is when you look at William Riker and his conditions for a federal republic to form. These are the military condition and the expansion condition and these must work together to shape the formation of the state. I would argue that the need for protection from a larger state has faded that colonialism is not an issue in the world so the military condition is not as important as it used to be. Which is a major reason why Yugoslavia has fallen apart. Now that the Soviet Union is no more Yugoslavia was able to revert back to its natural order and become smaller countries based on their separate religious and ethnic origins. I would love to hear anyone else's thoughts on the subject.
