Islam would only be involved with the state in so far as the State recognises its signifiance in Arab identity, history and culture. It may adopt some Islamic rhetoric to gain support in some areas and perhaps some very very religious sections may have sharia courts that citizens of that area may consent to. However state secularism and not atheism must be the ultimate goal of Arab society.

Not precisely, you see, there.are many Arabs like Maghrebis, Khaleeji arabs and Somali arabs who can very hardly be said to be of the same race. They have many different racial influences. But even if they were just an arab race, the thing is, the nation in my ideal society would not be defined by race, but by language, culture and territory, this is where I would agree with Ba'athists on what makes an Arab.

As a Marxist, such a socialist society exists to better the lives of the Arab working class by bringing them to power and thereby creating a better society. Socialism i believe must be a part of Pan-Arabism, because arguably it has been capitalism that divided the arabs the most (like capitalistic interests of the oil states) or the fact that imperialism of the arab people comes from capitalism in the eyes of many marxists. Would this socialist society make attempts to transition to communism or some greater next step? It depends on the material conditions both inside and outside this society. On one hand, the state must be strong to defend its proletarian state, on the other, the state decentralises as the people learn to administer themselves more locally. Unlike most Marxists i cannot say for certain whether communism is possible or achievable, what I do know however, is that this state would be a state controlled by the workers, and from that point on, technology might evolve, economic systems might evolve but there would be much less reaction from socialist society, because of the lack of class contradictions, such advancements would only help the masses.
