It's definitely not true today in 2010 because auto plants in 2021 cannot be 're-tooled' to make tanks. Also, US China conflict depends on entirely 'where' and 'over what' and what each nation is holding up it's sleeve. China does not have $50K rockets that it can use to down 'reasonably stealthy fighters' and as we have seen before, tactics combined with good tech gives overwhelming odds. For example, if (big 'if' but entirely plausible) the US can maintain air superiority in a particular region ... then it will basically maul whatever is before it. As just one example. China is building 100 subs that are a pretty big threat to any navy ... but we also don't know about advanced US tech that may render them completely moot. If there is no huge leverage by one side, it happens on land, and over a long time ... the then 'home team' will win.
