Unless we get a foreign policy that focuses on the use of power to treat the causes of problems vs. the symptoms of problems I'm afraid not much will change. That would be the mechanism that reworked the NSS and identified the required means and capabilities to fulfill that policy. Without it, there will probably be little serious change. Several former SecStates were quoated in an article in the Washington Post this morning about foreign policy recommendations.

As Zen and some others have pointed out - without legislation there is no forcing mechanism.
