This is incorrect.
Baathism is essentially fascism or more precisely Nazism, with the master race as Arab rather than Aryan.
An essential feature of Commmunism is its internationalist character, with the proletariat throughout the world united against their oppressors. Baathism very specifically is intended to unite racial Arabs (Muslim and Christian) against all other peoples.
It is fascinating that for five years the mass media has managed to constantly talk about the Baath party without ever mentioning its actual ideology. This is probably because they don't want the obvious parallels to Nazism to become apparent. Perhaps conservatives should start referring to the Baath party as the "Arab Nazi" party.
Actually there's really not much difference between Communism & Fascism/Nazism.
Throw out the jihadists with the Baath water..
