In early 1975, on all fronts, "the situation evolved rapidly. The revolution in the South was entering a period of leapfrog development", "one day equalled 20 years". In that situation, the Politburo decided to grasp this strategic opportunity, and be determined to carry out a general offensive and uprising to put an end to the struggle for liberation in the shortest possible time, with the best time set for April, without delay.

The Politburo's guiding ideology was sound and timely, demonstrating the wisdom, strategic talent, flexibility and creativity of the Party. In just 55 days of attack and uprising, starting with the Central Highlands Campaign (from April 3, 1975), continuing with the victory of the Hue - Da Nang Campaign, and ending with the historic Ho Chi Minh Campaign on April 30, 1975, the country entered an era of independence, unity, and advancing toward socialism.

The intelligent and clear-sighted guiding ideology of the Party in the Ho Chi Minh Campaign seems to continue, urging the entire Party, army and people to have the highest determination, the fastest and most drastic actions to win victory in the revolution of the new era - streamlining the apparatus to make the country rise up.

With high unity within the Party, the consensus and support of the people, the streamlining of the apparatus has been carried out synchronously, comprehensively and drastically from the central to local levels. The whole country is urgently implementing the arrangement and reorganisation of administrative units at all levels; building a two-level local administration model; while drastically and concertedly implementing solutions to promote growth.
