Never has the U.S. military been more reliant upon strategic partners for mission success. Operations and readiness requirements in Iraq, Afghanistan, Korea, Eastern Europe, and across the contingency spectrum all rely upon the Army’s ability to cultivate and leverage interoperability with others. In this multilateral world, Army leaders are empowered and most effective when they are able to think and act with a regional focus in concert with allies, and when they learn to link military education and experience with partners—both long-standing and evolving—in new and different ways.
