In contrast to the political unrest in Saigon, the Communist leadership in North Vietnam and in the VC were far more concerned about the best strategy to fight the South Vietnamese government and the Americans. While all leaders in Hanoi and in the VC shared the same goal of eventual reunification of their homeland, different factions within the Communist Party disagreed on the best method to achieve their desired goal. Members of North Vietnam's Politburo were divided by the issues surrounding the Soviet strategy of peaceful co-existence versus the Chinese strategy of supporting national liberation movements in emerging countries. Despite their differences of opinion, the Communist Party leadership ultimately made preparations for armed struggle in South Vietnam. From Hanoi's perspective, the military regime in Saigon was able to hold out because the Communist main forces were still not ready to fight a conventional war, so North Vietnam must focus on the development of its military force in the shortest period of time. In the meantime, however, the war must be kept at its current level in order to prevent the full involvement of the United States military.
