Five months and a bit to the November 2012 election.

The war in Iraq is over, the war in Afghanistan is adrift - but the underlying cause of both remains. OBL is dead yet the drone wars expand.

Our traditional European allies have never been weaker in living memory. The old order in the Arab world is changing, and the western Pacific grows in focus.

A military worn out by a decade of war is also looking at decreasing resources in a slugish economy.

Where do we prioritize? What is the best mix of strategy and programs to best prepare our military for the challenges of this century?

Which issues related to national defense will make it in to the 2012 contest? How do President Obama and Governor Romney differ in their views, plans, and priorities for our nation's military?

Our returning guest for the full hour will be Mackenzie Eaglen, Resident Fellow at the Marilyn Ware Center for Security Studies at the American Enterprise Institute.
