From my limited understanding it seems that the most noticable shift might be more of a push for human rights, possibly as a diversion to the usual military activities. This could signal a shift to Liberal IR theory, at least in rhetoric; but this theory is easily bent to justify military action as well. It looks unlikely that any real concerns about human rights and dictators will ever be advanced because of the economic instability of the world and the contributions of those who either: provide cheap labor and goods(China), or are strategically important. Given this, and some recent history, it seems that realist theory is most likely to be correct in the future. Which means we will likely remain in a state of sub-optimization with regard to our military interactions and alliances. Those atempting to implement democracies around the world have failed to take into account many obstacles, particularly the effect of religion, and the necessity of a secular government prior to a shift to democracy. In the end, it is not unthinkable that some Neocons would tweak their theories, to include lessons learned and some human rights concerns, in order to sell them to the democratic party.
