This issue Against Betrayal and Invasion captures the intense political, military, and ideological climate of Democratic Kampuchea as the nation prepared for total confrontation with Vietnamese revisionism. Detailing the Party's sharpened class line, the document emphasizes the ongoing efforts to eliminate internal enemies, especially within the Eastern Zone, where pro-Hanoi elements were facilitating infiltration. Emphasizing the mobilization of the entire population, the issue records the mass campaigns to increase rice yields amid the intensifying border conflict, with targets surpassing three tons per hectare in key regions. Most significant is its clear articulation of Kampuchea's revolutionary vigilance: rejecting peace overtures, denouncing Vietnamese expansionism, and affirming that the defense of national sovereignty required not only external resistance but the internal purification of the Party itself, ensuring that Kampuchea remained unbroken by the twin forces of imperialism and betrayal.
