French officers equated colonial nationalism with Communism's global advance [causal]
“We want to halt the decadence of the West and the march of Communism,” declared Argoud in court during the Barricades Trial of November 1960: “That is our duty, the real duty of the army. That is why we must win the war in Algeria. Indo-China taught us to see the truth.…” To men like “Boisfeuras” and Argoud the war against Communism was a permanent and unceasing phenomenon; while nationalism, in the Indo-Chinese and Algerian context, was largely equated with Communism.
XREF: Relates to broader Cold War framing of decolonization as anti-Communist struggle.
