I just want to add one more point if you allow me.
The situation in eastern Ghouta is different from that in Aleppo. Aleppo has access to different cities and towns not controlled by the Syrian regime. Eastern Ghouta is completely surrounded by the Syrian regime. That's the major concern of the population, the 400,000 civilians, because they don't want to go there. If they get out of Ghouta, they would have to go to the regime areas, where there are more than 500,000 estimated to be in prisons and tortured.
