The Center for Strategic and Budgetary Assessments (CSBA), a well-connected Washington defense think tank, just released a new analysis of future military trends around the Persian Gulf. Mark Gunzinger and Chris Dougherty, authors of “Outside-In: Operating from Range to Defeat Iran’s Anti-Access and Area-Denial Threats,” assert that over the next decade, Iran could acquire military capabilities that would rip up the assumptions that the U.S. military has used for its Persian Gulf planning over the past three decades. The authors conclude that the Pentagon needs to adapt to changing military circumstances in the region by devising new plans and redirecting investments into new capabilities.
