In that role, he served as the lead official in the development and rollout of the Department’s preeminent strategic planning guidance, the 2018 National Defense Strategy, which focuses the Department on the challenges to U.S. military superiority posed by China and Russia and therefore prioritizes sustaining the Joint Force’s warfighting edge against these major power competitors. Bridge also served as the lead official in the development of the 2017 Secretary’s Force Planning Priorities, which guided the review of and topline increases for the FY2019 defense budget, and the 2018 Defense Planning Guidance, which provided guidance for the development of the FY20 defense budget.

Earlier in his career he served for over five years in the U.S. Government at the Department of Defense, Department of State, and in the Intelligence Community working on a range of strategic forces, WMD, and intelligence reform matters, including service with the Coalition Provisional Authority in Iraq in 2003. Bridge has also served on the staff of a number of government commissions, including the 2014 National Defense Panel, the 2008-2009 Strategic Posture Commission, and the 2004-2005 President’s WMD Commission.
