The U.S. DoD is close to completing a European force posture review. The U.S. Navy Destroyers based in Rota, Spain should not be part of any reductions. These ships are key to defending Israel, contesting Russian and Chinese aggression, and defending U.S. economic interests.

Forward stationed DDGs are even more critical now that we are burning the readiness out of our Destroyer fleet with extended deployments in the Mid East. Removing them from Spain would make readiness measurably worse. @Brad_L_Bowman and I explain why

This does not bode well for France's commitment to increase defense spending. I doubt any protestors are yelling "tell me the plan for 3.5% GDP on core defense." Its critical that Europe's big economies (Germany, UK, Italy, France & Spain) get to 3.5 fast
