I think countries can, but there is a limit to how much debt you can have. It’s fine and even likely better for countries to have some deficit, but not $40T while also starting a war with Iran and imposing random tariffs that destabilize the world economy (+ attacking your allies, and all the other things Trump has done over the past decade, including adding an insane amount to the deficit)

For anyone not aware just how much: A quarter of it. A quarter of all US debt happened under Trump.
