These deployments have put the enemy in a considerably better position to launch an offensive either out of the Plaine or toward the Mekong. Coupled with the continuing development of Hanoi's infiltration apparatus, they also could supply a significant increment to the already substantial - and as yet not fully committed - Viet Cong strength in the northern provinces of South Vietnam.

Recently work on this line was given a higher priority, but it will still be several years before it is completed. Two. While this construction has been going forward, Peiping has maintained a fairly large ground force in both the Kunming and Canton…
