I'm familiar with Sykes Picot and the history of the Arab Revolt against the Ottoomans. I'm not sure its totally fair to characterize Hussein as a British agent but I'm open to more evidence on the matter.

If we are being honest, Antoun Saadeh had the most realistic analysis of nationhood in the region of "the Levant": everyone is Syrians basically and has been Syrians for thousands of years. These statelets are just parts of bilad al Sham.

However, I'm pretty sure that after the last century of sectarianism and Sykes Picot, that return is basically impossible now and I know for a fact that many people in "Natural Syria" (or Greater Syria) categorically reject the concept.

At this point in time Palestine is the central struggle for all Syrians, Arabs, Muslims, and justice-loving people on earth. And the flag is a universally recognized symbol for that struggle. So I'm going to respect the flag.
