This is where you are seriously mistaken. According to human rights watch, the rebels, have also caused plenty of grave human rights violation; and not just to soldiers but innocent victims. I know of personal stories so please drop the pretence that they are the innocent party; they are equally guilty and definitely more crazy than assad.
The fact that the west and arabs are funding, training, providing intelligence; makes them equal partners in crimes.
Hizbullah are not fooled; they know assad is not the real target; they know the oppressed syrians are not the real reason; after all he is not any less a dictator, or any less brutal than king abdullah of saudi and jordan, or king hammad of bahrain. Qatar kuwait etc… Infact assad is positively more liberal in comparison.
So what makes Assad any different? The fact that he is the link between iran and hizbullah. And every party I mentioned above, (including israel) has an interest in breaking this link. They have joined hands right now in this; and their real target is the ‘head of the snake’ as abdullah of saud put it.
A lebanon without hizbullah, an iran without the ayatullah is israels and the arabs biggest dream. They are the only real ‘opponents’ left, the rest have sadly fallen in line.
