As Donald Trump cheered the passage of his self-styled, and officially named, Big Beautiful Budget Bill through Congress this week, long-sown seeds of doubt about the scale and sustainability of US borrowing from the rest of the world sprouted anew.
Trump's tax-cutting budget bill is expected to add at least $3 trillion (£2.2 trillion) to the US's already eye-watering $37tn (£27tn) debt pile. There is no shortage of critics of the plan, not least Trump's former ally Elon Musk, who has called it a "disgusting abomination".
The growing debt pile leaves some to wonder whether there is a limit to how much the rest of the world will lend Uncle Sam.

We're trying the single guy life for a while again. So rest of the world we're breaking up, it's definitely us not you but we're leaving all our baggage to you and keeping some of the keys. You
Enjoy your orgies of on going cooperations and spirits of goodwill, you heathen scum.
Except for all the military bases literally everywhere.
