To what degree does the Constitution limit us in what some would call "playing geopolitics", but would I would argue is dealing with the realities in a complex world filled with challenges and threats to our well-being? There are many here, I would think, who might argue that the Founders' concern against standing armies and/or entangling alliances should limit our involvement around the world. IMO, the Constitution does no such thing. It merely limits the budgeting for the military (no more than two years as I recall), and sets the institutional checks on command. It says nothing about strategy or how we should deal with the world around us. We are faced with new and shifting challenges around the world. Obviously, jihadists are our most pressing concern. Their position and threat, though, is buttressed by a set of alliances, however loose, with rogue states. Those rogue states' themselves have different relationships with European states, Europe as a political entity, and with China. Europe itself increasingly sees its position as a counter-weight to our own strength and unilateral capabilities and interests and seeks its own relationships with others such as Russia and China. China's economic and military position grows stronger. Does the Constitution limit us in dealing with these players? Should the Founders' perception of our best interest govern us separately from the Constitution to the extent the two differ?
