Our forces are balanced and ready, mobile and diverse. Our allies trust our strength and our adversaries respect it. But the challenge is unceasing. … - Lyndon B. Johnson

For many years we have been engaged in a struggle in Southeast Asia to stop the onrushing tide of Communist aggression. We faced it when the Greek Communists were a few miles out of Athens a few years ago. We faced it when we had to fly zero weather into Berlin to feed the people when that city was beleaguered and cut off. We faced it on the Pusan Peninsula when our men were fighting for the hills of Korea and everybody said, "They are not worth it." We fight Communist aggression the same today in Southeast Asia. This tide threatens to engulf that part of the world, and to affect the safety of every American home. It threatens our own security and it threatens the security of every nation allied with us. The blood of our young men this hour is being shed on that soil. They know why they are there. I read 100 letters from them every week. They do not have the doubts that some at home preach. They have seen the enemy's determination. They have felt his thrust trying to conquer those who want to be left alone to determine their government for themselves, but whom the aggressor has marched over to try to envelop. Our fighting men know, from the evidence in their eyes, that we face a ruthless enemy. You make a serious mistake if you underestimate that enemy, his cause, and the effect of his conquest. They know from the carnage of the enemy's treacherous assaults that he has no feelings about deliberate murder of innocent women and children in the villages and the cities of South Vietnam. They are not misled by propaganda or by the effort to gloss over the actions of an enemy who, I remind each of you, has broken every truce, and who makes no secret whatever of his intention and his determination to conquer by force and by aggression his neighbors to the south. At the same time, during these past 4 years, we have made remarkable strides here at home. We have opened the doors of freedom, full citizenship, and opportunity, to 30 million minority people, and we have sustained the highest level of prosperity for the longest period of time ever known. But the time has come this morning when your President has come here to ask you people, and all the other people of this Nation, to join us in a total national effort to win the war, to win the peace, and to complete the job that must be done here at home. I ask all of you to join in a program of national austerity to insure that our economy will prosper and that our fiscal position will be sound.

The first area of this increasing strength is our ability to deter atomic destruction. In the past 3 years we have increased our nuclear power on alert 2½ times, and our nuclear superiority will continue to grow until we reach agreement on arms control. We have now more than 1,000 fully armed ICBM's and Polaris missiles ready for retaliation. The Soviet Union has far fewer, and none ready to be launched beneath the seas. We have more than 1,100 strategic bombers, many of which are equipped with air-to-surface and decoy missiles to help them reach almost any target. The Soviet Union, we estimate, could with difficulty send less than one-third of this number over targets in the United States. Against such force the combined destructive power of every battle ever fought by man is like a firecracker thrown against the sun.

We are the children of revolution. The history of America is the history of continuing revolution. That revolution has conquered a continent and it has extended democracy. It has given us unmatched mastery over nature, and it has given us the tools to conquer material wants. It has set the stage for a new order of society--devoted to enriching the life of every human being on a scale never before thought possible. True, these revolutions have been peaceful; but they have shaken the entire globe. Our struggle against colonial rule is still reshaping continents. Our achievements have lifted the hopes and ambitions of men who live everywhere, lifted him for a better life. Our political ideas have helped to make "freedom" a rallying cry in every corner of the world. And if the consequences of these forces sometimes cause us difficulty or create danger, then let us not be dismayed. For this is what America is all about; to show the way to the liberation of man from every form of tyranny over his mind, his body, and his spirit. We cannot, and we will not, withdraw from this world. We are too rich, too powerful, and too important. But most important, we are too concerned.
