There was a US branch of FTX that SBF has been saying "has funds to make people whole" but is still under Chapter 11 "because he made a mistake declaring bankruptcy", and that branch in independent of the international exchange. US customers still can't withdraw their funds. I am not sure people want the US to "lead" everything as much as they want, as people that invested money on a US company, for the government to help them get it back after it was, allegedly, stolen.
