(CNN) - Vice President Joe Biden emphasized a "new tone" in Washington and around the world as he delivered his first major speech Saturday in Munich, Germany.
Biden told delegates at a security conference that the United States will work "preventively, not pre-emptively" whenever possible to avoid conflict, and will at the same time "vigorously defend" the nation's security.
He also said the United States will do everything possible to end the threat posed by extremists.
"We reject as false the choice between our safety and ideals," Biden told the Munich Security Conference audience, which included German Chancellor Angela Merkel and French President Nicolas Sarkozy. "America will vigorously defend our security and our values, and in doing so we will all be more secure."
That policy will be in force at Guantanamo Bay detention camp, the U.S. prison that the Obama administration intends to close, Biden said.
"America will not torture. We will uphold the rights of those we bring to justice," Biden said.
