Tom Lantos Congress activity

I can't really point one theme in his political activity, but the care for human rights was a dominant issue in his work. Lantos had participated in several protests and acts against the Sudanese government, demanding to stop the genocide in Darfur.

I believe the following answers your question which is an existential one. In his eulogy, Elie Weisel said: "If we remember suffering, our own and that of others, only to bring more suffering into the world, we would betray it. The only response to the tragedy is simply to remember it for the sake of our children, and children everywhere. Simply, because it happened, it must never happen again anywhere to anyone, and that was, of course, the meaning of your (Tom Lantos') endeavors, the goal of your (Tom Lantos') battles". This is from an article in the Friday February 15 Jerusalem Post (first section, page 9) : "A man of valor: Friends, colleagues pay tribute to Tom Lantos in Washington" by Hilary Leila Krieger.

Since 1989, the Speaker of the House has appointed Tom Lantos a Member of the United States Holocaust Memorial Council. As the only survivor of the Holocaust ever elected to Congress, he brings a unique point of view to this position. The Council is responsible for the development of the Holocaust Memorial Museum on the National Mall in Washington, D.C., and for creating programs to honor victims of the Holocaust. It also has responsibility to call attention to current instances of genocide and conducts programs to encourage tolerance and respect for law.
