Zeid Raad al-Hussein isn't afraid to speak his mind.
The U.N. high commissioner for human rights has taken on some of the most powerful countries in the world. He has compared populist movements in Europe to the Islamic State, and he called the European Union "inhumane" for its policy of helping the Libyan coast guard intercept and return migrants.
He has suggested that President Donald Trump is a demagogue enabling ethnic nationalism and has denounced his refugee ban as "grossly irresponsible." He has warned that genocide is imminent in Chinese-backed Burma and condemned Russia for its actions in Crimea and Syria.
His fans describe him as brave and tenacious, a strong advocate for human rights at a critical moment.
But it has been a tough battle, one that became even more challenging after Trump's election. Past U.S. administrations have emphasised the importance of human rights, at least rhetorically. Trump, however, has signalled that he is uninterested in prioritising international norms and commitments, instead advocating for "America First."
