population control in any future negotiations or reunification effort. The fighting that erupted was not small in scale. The three-phase North Vietnamese "Land-grabbing-and population nibbling" campaign, for example, included four division-sized attacks to seize strategically advantageous positions. The International Commission of Control and Supervision (ICCS), established by a protocol of the Paris agreement, had been assigned the task of monitoring the implementation of the cease-fire. The principles of consultation and unanimity among the members, however, doomed any effort to control the situation or to stop cease-fire violations, and the ICCS ceased to function in any meaningful way within a few months of its establishment. At the end of 1973, there was serious debate among the Hanoi leadership over future military policy as the Central Committee of the Communist Party of Vietnam convened to assess the progress of its efforts in the south. General Văn Tiến Dũng, PAVN chief of staff, and Defence Minister Võ Nguyên Giáp strongly urged the resumption of conventional military operations, warning that increasing passivity would affect the morale of the army. Premier Phạm Văn Đồng, however, feared resuming operations would drain vital resources needed for reconstruction in the north. The final result of this debate was Resolution 21, which called for "strategic raids" on South Vietnamese forces in order to regain territory lost to the ARVN since the conclusion of the Peace Accords and to test the reaction of both the South Vietnamese military and the American government. The first blows of the new policy were delivered between March and November 1974, when the communists attacked ARVN forces in Quảng Đức Province and at Biên Hòa. Hanoi's leaders watched closely and anxiously as strikes by American B-52 Stratofortress bombers failed to materialize. During these operations, however, PAVN retook the military initiative, gaining experience in combined arms operations, depleting ARVN forces, causing them to expend large quantities of ammunition, and gaining avenues of approach and jump-off points for any new offensive. South Vietnamese President Nguyễn Văn Thiệu had made his position on the cease-fire agreement quite public by proclaiming the "Four Nos": no negotiations with the communists; no communist political activities south of the Vietnamese Demilitarized Zone (DMZ); no coalition government; and no surrender of territory to the North Vietnamese or Provisional Revolutionary Government (PRG) – policies which all but abrogated the Paris Accords. Thiệu still believed the promise made by President Richard Nixon to reintroduce American
