Financing our empires is only possible when the lenders are capable of paying our loans back. Obama, Biden et al. made a huge mistake betting on Ukraine thinking Russia wouldn’t take the resources in the South and in the East. And the West of Ukraine is useless. US is losing money on a bad bet and it doesn’t have much left. There’s always an option to default on our debt, so it’s not like we’re screwed, but that’s only possible to do once.
