I think it's the opposite. China, and the rest of Asia, has far more at stake with this conflict. Why would the US need to win with near zero losses? Chinese naval facilities and infrastructure would be the first targets in a conflict. American naval construction is half a world away. The biggest risk for the US is anti-war activism at home, which is slowly being rooted out ahead of time with the propaganda today.
if the US doesn't win with near 0 losses but gets crippled instead, then it signals to everyone that US isn't invincible and that in fact, inflicting harm upon it in revenge is possible and maybe will be the only chance to do so.
That means Iran might start hitting US forces in the Middle East and they can't do anything about it without invading a country 2x the population and area of Ukraine with GDP per capita 5x higher than Ukraine and the geography of Afghanistan. What are they seriously gonna do about it if Iran decides to sink 5th fleet inside Persian Gulf while its attempting to transit out of the Gulf?
That means Russia might escalate to tactical nukes in Ukraine and they can't do anything about it without using their own nukes, which would lead to MAD. What are they gonna do about it, bomb Russia with the F-35s they're transferring to the SCS?
Everyone everywhere would see it as a green light that they can ignore the wishes of the US because they've lost the capability to project power.
a war with China means also global hyperinflation on almost every product, global famine (
), global economic depression, shortage of everything. Sanctioning Russia with a Canada sized economy has led to 50%+ inflation on gas. What do you think is going to happen when an economy bigger than the entire EU is sanctioned, especially when it is the largest fertilizer precursor producer in the world?
they can keep strikes on Chinese shipyards? How if their power projection capabilities are crippled? If in the course of the war they are damaged - such as losing 4-5 carrier groups, bases are damaged to only 20-30% sortie rate and half their strategic air assets like tankers and bombers get shot down, by what mechanism are they going to keep hitting a highly hardened delayed effect target?
And the shipyard is only the final assembly point, the actual module fabrication happens elsewhere. The shipyard is just concrete and steel.
They also don't have the capability to hit Chinese aerospace or ground force industries without nukes, since they're all 2000+ km inland. Range of tactical air means they'll have to refuel over China to even launch missiles, B-1s and B-52s have no chance of surviving long enough to launch against inland targets, B-2s that do anything other than hit nuclear silos will alert fighter intercepts with IRST, hitting one set of nuclear silos means full strategic launch. so SAMs, ammunition, fighter parts, etc. will keep being built and keep inflicting damage on them.
Basically, the end result will be the real world version of what they think Ukraine is doing to Russia - destroying the global economy, grinding their military into oblivion, making them look like a giant joke, and emboldening their enemies.
