Trump has rightfully been critical of the Iranian nuclear agreement, arguing that it's a "bad deal" in which the U.S. gave up its leverage over Tehran without even addressing the terrorism issue. But Trump is repeating that error when he decided to lift sanctions on Sudan without even mentioning Sudan's documented history of killing Americans serving their country. Sudan has given every indication that, even when the financial judgments against it become final, it will follow the same tack as Iran, flouting the U.S. court judgments and avoiding making the payments ordered by the courts. Therefore, the only way that the victims' families will receive their overdue compensation is through pressure from the United States--pressure that Trump just relinquished. Any relief from sanctions should have been accompanied by a firm and enforceable commitment from Sudan to promptly pay final judgments issued by the U.S. courts or resolve the claims before judgment.
