On all fronts the USA is way behind China.

The USA has lost the ability to build physical infrastructure because its entire industrial base has been run down and neglected over decades of neoliberal financialisation and outsourcing to offshore providers.

The USA has lacked a cohesive and strategic industrial and economic development plan. Free markets don't plan for a nation state- only a government can do this but the neoliberal ideology has failed to plan and build the plant, skills and infrastructure required for the US maintain global hegemony. China spent four decades investing strategically in developing its stranglehold over rare earth refining...and multiple other strategic supply chains especially related to energy production and efficiency. Now the USA cannot fight a war of any scale for at least a decade because China hold a monopoly over the supply of the rare earths supply chains needed to build modern war materiel.
