There were some in South Vietnam who wished to force Communist rule on their own people. But their progress was slight. Their hope of success was dim. Then, little more than 6 years ago, North Vietnam decided on conquest. And from that day to this, soldiers and supplies have moved from North to South in a swelling stream that is swallowing the remnants of revolution in aggression. As the assault mounted, our choice gradually became clear. We could leave, abandoning South Vietnam to its attackers and to certain conquest, or we could stay and fight beside the people of South Vietnam. We stayed. And we will stay until aggression has stopped. We will stay because a just nation cannot leave to the cruelties of its enemies a people who have staked their lives and independence on America's solemn pledge--a pledge which has grown through the commitments of three American Presidents. We will stay because in Asia and around the world are countries whose independence rests, in large measure, on confidence in America's word and in America's protection. To yield to force in Vietnam would weaken that confidence, would undermine the independence of many lands, and would whet the appetite of aggression. We would have to fight in one land, and then we would have to fight in another--or abandon much of Asia to the domination of Communists. And we do not intend to abandon Asia to conquest. Last year the nature of the war in Vietnam changed again. Swiftly increasing numbers of armed men from the North crossed the borders to join forces that were already in the South. Attack and terror increased, spurred and encouraged by the belief that the United States lacked the will to continue and that their victory was near. Despite our desire to limit conflict, it was necessary to act: to hold back the mounting aggression, to give courage to the people of the South, and to make our firmness clear to the North. Thus. we began limited air action against military targets in North Vietnam. We increased our fighting force to its present strength tonight of 190,000 men. These moves have not ended the aggression but they have prevented its success. The aims of the enemy have been put out of reach by the skill and the bravery of Americans and their allies--and by the enduring courage of the South Vietnamese who, I can tell you, have lost eight men last year for every one of ours. The enemy is no longer close to victory. Time is no longer on his side. There is no cause to doubt the American commitment. Our decision to stand firm has been matched by our desire for peace. In 1965 alone we had 300 private talks for peace in Vietnam, with friends and adversaries throughout the world. Since Christmas your Government has labored again, with imagination and endurance, to remove any barrier to peaceful settlement. For 20 days now we and our Vietnamese allies have dropped no bombs in North Vietnam.
