SAN FRANCISCO, Sep 02 (IPS) – Joe Biden provided a stirring soundbite days ago when he spoke from the White House just after suicide bombers killed 13 U.S. troops and 170 Afghans at a Kabul airport: “To those who carried out this attack, as well as anyone who wishes America harm, know this: We will not forgive. We will not forget. We will hunt you down and make you pay.”
