The common wisdom is that Donald Trump's foreign policy will be a disaster for human rights. Certainly his penchant for embracing autocrats and breaching norms bodes poorly, such as his outrageous proposal to force two million Palestinians out of Gaza - which would be a blatant war crime - or his suggestion that Ukraine is to blame for Russia's invasion. But Trump also likes to cut a deal, as shown by his paradoxically positive role in securing the current (precarious) Gaza ceasefire. If Trump the dealmaker can be nudged in the right direction, he might, against all odds, be brought to play a productive role for human rights.

As executive director of Human Rights Watch, I spent more than three decades devising strategies to pressure or cajole leaders to better respect rights. I have dealt with brutal dictators, self-serving autocrats and misguided democrats. My experience shows that there is always an angle - something the leader cares about - that can be used to steer them in a more rights-respecting direction.
