North Vietnam sent arms and supplies south by way of a network of jungle paths known as the Ho Chi Minh trail. The trail wound through the countries of Cambodia and Laos, bypassing the border between North and South Vietnam. Because the trail passed through countries not directly involved in the war, President Johnson refused to allow a full-scale attack on the trail to shut it down.
