More or less correct yeah, and I have no idea what Operation Sandman is. It sounds like bologna.
Foreign nations have zero incentive to dump Treasury holdings, particularly as most other sovereign credit looks like shit in comparison. Higher inflation elsewhere, more credit/default risk, etc.
Treasuries owned by anyone are sold in the open market, so natural buyers would also emerge. The likelihood they all dump? Zero. No evidence for it
