Introduction

	"My fellow Americans. I was informed this morning that troops of the Republic of Vietnam, responding to an attack on their positions from across the so-called Demilitarized Zone, have pursued elements of the North Vietnamese Army into the bases from which those treacherous attacks were launched. The Communist aggressors have not learned the lesson that the people of America are resolute in the defense of freedom. They will learn that lesson now. I have directed American armed forces to act in support of our South Vietnamese allies in the exercise of their right of hot pursuit. I warn the aggressors not to interfere with this fully justified defensive operation. If enemies challenge American resolve, they will feel our might in a direct way. As a palpable warning to the enemies of freedom, I inform them that as of this date there are no more sanctuaries. Even as I speak, troops of America and of our allies have crossed the boundaries that our adversaries have scoffed at since their invasion began in 1956. We are striking at the bases of the communist aggressors in Cambodia and Laos, destroying the materiel stockpiled to subvert the government of the Republic of Vietnam. And I issue this warning to the leaders of China and the Soviet Union: watch where you step. If you become directly involved in this attempt to conquer a member of the free world and an ally of America - watch out! There's a bear trap ready to snap, and there's room in its jaws for you as well as you lackeys in Hanoi!"
	President Lyndon Baines Johnson March 31st, 1968
