I will LOL when the ChiComs grab all of the USA manufacturing facilities in the name of the people and give US companies a "So Solly Charlie". Would be so good.
If China did that, they can forget redeeming those Treasury notes.
The second casualty will come as we stop paying on our debt. Without that constant inflow of cash they can't survive more than 60 days.
I don't see any upside for the ChiComs to start a shooting war when they can just buy whatever they really want.
And then we default on any bonds the chicoms have in retaliation. If we contain the fighting to air/sea and limited land engagements on islands we kick their butts. We also get the Japanese and other Asian countries involved and we should certainly continue to cultivate a closer relationship with India as a counterbalance in man power alone against the chicoms. The wild card is they may be crazy enough to go nuclear rather than face a humiliating lose. Our problem is the current wussie in chief.
