ISIS and other extremist groups across the Middle East are enslaving, killing and uprooting Christians, and there's no end in sight.

Eliza Griswold, author of a New York Times article titled Is This the End of Christianity in the Middle East?, went "On The Record" with Greta Van Susteren to discuss the horrors that Middle Eastern Christians are experiencing.

She revealed that since the U.S. invasion of Iraq in 2003, the number of Christians in the nation has dropped from 1.5 million to 300,000.

She added that it's not just killings that put Christianity in danger in the region, but Christians' inability to have a homeland.

"The degree of suffering stunned me," Griswold said. "I thought of the Holocaust."
