China doesn’t need its military to hurt us; it already builds so much for us that cutting off trade would hurt. Add in calling in our debt to either hyperinflate the currency or demand the right to buy off shore oil leases where Americans have been banned or buy up federally owned “wilderness” to mine or farm as they are doing in Africa today.
The US could just cancel the bonds owed to China on the grounds of the war.
Cheers!
