Washington, D.C. — SOME years ago, I heard Natan Sharansky, the human rights icon, recount how he and his fellow refuseniks in the Soviet Union took renewed courage from statements made on their behalf by President Ronald Reagan. Word had reached the gulag that the leader of the most powerful nation on earth had spoken in defense of their right to self-determination. America, personified by its president, gave them hope, and hope is a powerful defense against oppression.

As I listened to Mr. Sharansky, I was reminded how much it had meant to my fellow P.O.W.s and me when we heard from new additions to our ranks that Mr. Reagan, then the governor of California, had often defended our cause, demanded our humane treatment and encouraged Americans not to forget us.

In their continuous efforts to infect us with despair and dissolve our attachment to our country, our North Vietnamese captors insisted the American government and people had forgotten us. We were on our own, they taunted, and at their mercy. We clung to evidence to the contrary, and let it nourish our hope that we would go home one day with our honor intact.

That hope was the mainstay of our resistance. Many, maybe most of us, might have given in to despair, and ransomed our honor for relief from abuse, had we truly believed we had been forgotten by our government and countrymen.
