US insolvency requirements are "due process of law".  It's up to those who don't believe that US insolvency law should be applied in this case to petition the court with on point arguments and case law supporting that assertion - the cost of defending against any such actions will come out of the bankrupt estate.  Unless USD holders can establish that they're secured or preferential creditors as defined by US insolvency law, there are no legal grounds on which they can be paid in full in preference to other unsecured creditors without the agreement of those other creditors.
