アラブ社会主義
The disillusionment felt among party members on the pan-Arab project, led to the radicalization of the party's interpretation of socialism. Yasin al-Hafiz, a former member of the Syrian Communist Party, was an early frontrunner for the party's radicalization. While he didn't oppose the pan-Arab project, he wanted to turn the concept of Arab socialism into a scientific and revolutionary socialist ideology which adapted Marxism to local conditions. Jamal al-Atassi, who had been a moderate socialist for most of his life, called for the renunciation of Arab socialism in 1963 and the adoption of a "virtually Marxist concept of socialism" by claiming that class struggle was the moving force in society.
