As we speak, more than 150,000 troops are positioned in nearly 80 countries. Hundreds of U.S. bases serve as deterrents against adversaries, others as an assurance to allies, and still more as stops along a global military supply chain.

What are the intended and unintended consequences of these deployments? What exactly are we trying to accomplish?

Helping us to consider that question are:

• Michael McNerney, the Associate Director of the International Security and Defense Policy Center at the Rand Corporation.

• David Vine, author of the 2015 book, "Base Nation: How U.S. Military Bases Abroad Harm America and the World."
