"Last night I announced to the American people that the North Vietnamese regime had conducted further deliberate attacks against U.S. naval vessels operating in international waters, and I had therefore directed air action against gunboats and supporting facilities used in these hostile operations. This new act of aggression, aimed directly at our own forces, again brings home to all of us in the United States the importance of the struggle for peace and security in southeast Asia. Aggression by terror against the peaceful villagers of South Viet-Nam has now been joined by open aggression on the high seas against the United States of America. The determination of all Americans to carry out our full commitment to the people and to the government of South Viet-Nam will be redoubled by this outrage. Yet our response, for the present, will be limited and fitting. We Americans know, although others appear to forget, the risks of spreading conflict. We still seek no wider war."
