Some Russian dissidents mistrusted the Zionist movement as particularistic and unpatriotic, fearing it would distract from their broader human rights agenda. Not Sakharov. He supported the refuseniks because he recognized the right to emigrate as a gateway to democratic entitlement that opens everyone to embracing freedom in a closed society.

By the mid-1970s I was serving as Sakharov’s spokesman, and I remember after yet another friend of ours had been sentenced to prison, he told me: “They want us to believe there’s no chance of success. But whether or not there’s hope for change is not the question. If you want to be a free person, you don’t stand up for human rights because it will work, but because it is right. We must continue living as decent people.”

Sakharov’s decency made him a moral compass orienting not just the East, but also the West. He insisted that international relations should be contingent on a country’s domestic behavior — and that such a seemingly idealistic stance was ultimately pragmatic. “A country that does not respect the rights of its own people will not respect the rights of its neighbors,” he often explained.

As Sakharov and his fellow dissidents in the 1970s and ’80s challenged a détente disconnected from human rights, Democrats and Republicans of conscience followed suit. Jimmy Carter and Ronald Reagan disagreed about many specific policies, but both presidents linked human rights and foreign policy. President Carter treated Soviet dissidents not as distractions but as respected partners in a united struggle for freedom. President Reagan went further, tying the fate of specific dissidents to America’s relations with what he called the “evil empire.”

Approaching the fight to win the Cold War as a human rights crusade as well as a national security priority energized Americans. It reminded them that, regardless of the guilt and defeatism of the Vietnam War or the shame and cynicism of Watergate, the country remained a beacon of liberty.

This anniversary of Andrei Sakharov’s heroic essay comes during similarly dark days for the United States.

Despite the dramatic discontinuities between Donald Trump and Barack Obama, in divorcing human rights from foreign policy President Trump is following President Obama’s lead.
