Koda defines the A2 and AD threat separately, with ASBMs, submarine forces, counter-domain superiority as A2 efforts targeting U.S. force flow into the region, and land attack missiles, special force sabotage, island seizure as AD efforts targeting U.S. forces already postured within the region. His prescription is to develop countermeasures such as missile defense capabilities to offset the A2/AD threat, while leveraging the alliance’s current advantages to exploit China’s vulnerability and impose cost.
