Christiane Amanpour hosts “God’s Warriors” (8 p.m., CNN), a three-night examination of how religious zealots from the three major faiths have become a major political force in the United States, Israel and the Islamic world.

“Warrior” is divided into Judaism (tonight), Islam (Wednesday) and Christianity (Thursday), but there is plenty of overlap.

Tonight’s installment chronicles the rise of the religious-settlement movement in Israel. After Israel’s rapid victory in the 1967 Six-Day War, the isolated country was suddenly in the custody of a large Palestinian population in newly occupied territory.

While some Israeli diplomats saw them as means of trading land in negotiations, religious activists considered these territories a fulfillment of biblical prophecy. They began to improvise settlements, dividing Israelis and causing outrage in the Arab world.

The United States has long considered the settlements illegal and an impediment to peace. But Amanpour visits with American citizens who have devoted their lives to raising funds to permanently settle the occupied territories with Jews.

More recently, Evangelical Christians have joined the fundraising. And even though contributors to these charities are defying American foreign policy, some receive a tax deduction from the IRS.

Amanpour interviews Noa Rothman, the granddaughter of Israeli Prime Minister Yitzhak Rabin, whose 1993 peace treaty with the PLO upset many in the pro-settlement ranks. A militant Jewish fundamentalist assassinated Rabin in 1995.

But Rabin was not the only leader to pay the price for negotiating. In 1981, Islamic militants gunned down Egyptian president Anwar Sadat. Wednesday night, Amanpour will interview Kamal el-Said Habib, a jihadist who was part of that murder plot.

“Warrior” also includes interviews with former President Jimmy Carter, who negotiated a peace treaty between Sadat and Israeli Prime Minister Menachem Begin. Carter, whose election in 1976 and defeat in 1980 were affected by Evangelical voters, also discusses the role of religion in American politics.

The Rev. Jerry Falwell, who died May 15, sat down with Amanpour a week before his death. Thursday night’s “Warrior” includes Falwell’s last interview, during which he defends and repeats his controversial assertion that the Sept. 11, 2001, attacks were assured, if not deserved, because a wrathful God had removed his “protective shield” from a sinful United States.

¢ The month of Diana retrospectives continues. “Special Investigations Unit: Growing Up Diana” (7 p.m., CNN) recalls the doomed princess’ fractured family and unhappy youth.

Correspondent Soledad O’Brien interviews Princess Diana’s childhood nannies, friends and family members and asks them how this shy girl became the media-savvy survivor who upstaged her Windsor tormentors to became an outspoken advocate for AIDS research and the banning of land mines, among other causes.

¢ Director Kenneth Branagh adapts Shakespeare’s “As You Like It” (8 p.m., HBO) and moves the action and the Forest of Arden to 19th-century Japan.
