Legally bond ownership establishes no land claim or are you speaking of morally?
Yep, but more generally.
Because the bonds were purchased by China, the debt is essentially between sovereign nations. US treasury bonds were not specifically designed to accomplish this type of lending, so there is not a lot of precedent here.
Historically, repudiated debt between sovereign nations, without agreement, has led to serious consequences, (read: war), so I'd like to NOT have that happen.
Ironic, the Chicoms don't want socialist entitlement policy to devalue their investment.
