Vice President Joe Biden used the strongest language to date from the Obama administration in response to the beheading of American journalist Steven Sotloff by ISIS militants.
Speaking at the Portsmouth Naval Shipyard in Kittery, Maine, on Wednesday, the vice president paid tribute to Sotloff before vowing justice against his killers.
"The American people are so much stronger, so much more resolved than any enemy can fully understand," Biden said. "As a nation we are united and when people harm Americans we don't retreat, we don't forget. We take care of those who are grieving and when that's finished, they should know we will follow them to the gates of hell until they are brought to justice because hell is where they will reside."
