 U.S. must prepare for war with China and Russia. Congress. Washington needs to urgently update and expand both its nuclear arsenal and the conventional military in order to face the combined might of Moscow and Beijing. The Congressional Strategic Posture Commission argued in its final report, the United States and its allies must be ready to deter and defeat both adversaries simultaneously, the commission said. The U.S. led international order and the values it upholds are at risk from the Chinese and Russian authoritarian regimes. While the commission has not identified any specific evidence of Russia and China working together, we worry there may be ultimate coordination between them in some way which gets us to this two-war construct. A senior official involved in the report told Reuters on condition of anonymity. The current U.S. national security strategy calls for defeating one major adversary while deterring another. The commission argued that the combined threat from China and Russia will become acute as early as 2027, so decisions need to be made now in order for the nation to be prepared. The 131 findings and 81 recommendations in the report amount to the need for massive expansion of both the conventional armed forces and the nuclear triad. The report demands more of the B-21 stealth bombers and Columbia-class ballistic missile submarines. The B-21 is still in development and is expected to enter service by 2027 at the earliest. The first two Columbia-class subs are under construction and are expected in 2030. The U.S. Navy has planned to order 12 to replace the 18 Ohio-class boats currently in service.
