KITTERY (MAINE (TIP)): Vice-President Joe Biden on September 3 said America will follow the terrorists who posted videos showing the beheading of two journalists “to the gates of hell.” Biden said the Islamic State militant group responsible for beheading James Foley and Steven Sotloff won’t intimidate the United States.

“The American people are so much stronger, so much more resolved than any enemy can fully understand,” Biden said at the Portsmouth Naval Shipyard in Maine. “As a nation, we’re united. And when people harm Americans, we don’t retreat, we don’t forget.”

A videotape showing Sotloff’s murder was broadcast on September 2, two weeks after the same group released a video showing Foley’s killing.

“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,” Biden said. “Because hell is where they’ll reside.” Biden, a potential 2016 Democratic candidate for president, has used “gates of hell” before, invoking it in an October 2012 vice presidential debate when talking about the killing of Osama bin Laden.

Foley was from New Hampshire and Sotloff attended school there, bringing their killings close to home for many in attendance at Biden’s speech. The shipyard employs many New Hampshire residents.
