Stewart was responding to a question concerning reports this week that US forces had seized a key Islamic State, or Daesh, leader in Iraq. He cited instructions in the US Army Field Manual, which focus on establishing rapport with the prisoner.
“That type of [rapport-based method] works,” Stewart pointed out. “It gives good insights that lead to other operatives. It gives us insights into how the network operates, so there’s value there and ultimately that could prevent terrorist attacks.”
President Barack Obama has described the scandal-tainted method of waterboarding as torture, and ended the practice that was widely used following the September 11, 2001 terrorist attacks on the United States.
Torture has become an issue in the US presidential campaign, with Republican frontrunner Donald Trump advocating waterboarding and even harsher methods in questioning terrorist suspects.
