US is scaling down its forces in the Middle East and building up its forces in the Pacific and by 2025, US will have new weapon systems that will negate all advantages that China has such as their Carrier Killer Missile.
By 2025, 60% of all US forces will be in the Pacific. And not only that, South Korea, Japan, Australia, Philippines, Vietnam, Taiwan, Thailand, Singapore and others are all US allies and will join forces to fight China and with years of buying Arms from USA, all of them will very lethal foes to China.
Any China vs USA war in 2025, will look like what happened to Iraq during the Gulf War, when all of the American Arab Allies joined forces to fight Saddam.
