Infrastructure funding is political influence. Non-warry stuff.
But if you want to wage war on China be prepared to go back to the 50s. China and its immediate neighbours make everything. And have done for decades. No country has the standing manufacturing capability (facilities, machinery or trained/robotic workforce) to replace what China does for them. Some other Asian countries manufacturer electronics and India and Pakistan do textiles like nobody's business.
This is where that influence from earlier came in. They've traded cash for foreign government bonds to ensure great tariffs and to stop protectionist policies. They pegged their currency to ensure their exports undercut everybody else.
Automobiles are pretty much the last serious manufacturing done in market countries... And where do you think many of those source their parts and steel from?
So yeah, you piss off China and they have the physical wherewithal to embargo almost all material imports. Your economy dies overnight.
You take back a bridge and a nuclear power plant. Big whoop. What's your next move?
