Biden: "new tone" or "newspeak"?

Biden promises 'new tone' in U.S. foreign affairs

Excerpt:

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.
