Would a global famine be enough to get rid of all the Muslims in Europe? They aren't particularly well adapted to cold environments, they require vitamin D supplementation from their diets to function well, so if that was cut off would they all die? The u.s. is the largest exporter of food by a large margin, would the embargo of food exports be enough to kill them off? Also could we simply stop exporting food and fertilizer to the middle east and starve them out?
