Meanwhile, the Khmer Krahom fell under the control of its most fanatical members, led by Pol Pot and Ieng Sary.  They were beyond the control of Hanoi and sought to completely annihilate Cambodian society and restart from scratch.  When they besieged the capital again, the US again launched a bombing raid against Communist forces.  The US Seventh Air Force argued that the bombing prevented the fall of Phnom Penh in 1973 by killing 16,000 of 25,500 Khmer Rouge fighters besieging the city.

The communist leaders had expected that the ceasefire terms would favor their side. But Saigon, bolstered by a surge of U.S. aid received just before the ceasefire went into effect, began to roll back the Vietcong. The communists responded with a new strategy hammered out in a series of meetings in Hanoi in March 1973, according to the memoirs of Tran Van Tra.

As the Vietcong's top commander, Trà participated in several of these meetings. With U.S. bombings suspended, work on the Ho Chi Minh Trail and other logistical structures could proceed unimpeded. Logistics would be upgraded until the North was in a position to launch a massive invasion of the South, projected for the 1975–1976 dry season. Trà calculated that this date would be Hanoi's last opportunity to strike before Saigon's army could be fully trained.
