Yes, it is time for al-Assad to go. Aleppo has been reduced to ruins and may never be restored. The devastation in Aleppo can be directly attributed to al-Assad, and he must relinquish leadership if Aleppo and its people are to have any chance of recovering the city that used to exist.
This man has used chemical weapons against his own people including children. The images on television watching people die from the use of chemical weapons are heartbreaking. He is an inhumane dictator. He is trying to show how powerful he is by killing people in the most disgusting way possible, which is the only way dictators do things. He has to go, now.
When it comes to Al-Assad being "let go" regarding the devastation in Aleppo, if the man is not making any real progress in trying to make things better and possibly fix the moral of the torn up city, then I think he should be removed from his current position in office.
Yes, it is time for al-Assad to go, because the people in Syria are suffering. The conflict there has been long. Al-Assad cannot control the suffering there, nor does he even care that his people are dying. There is a humanitarian crisis in the country. Al-Assad has had a chance to fix things and he has not.
Although Assad may not be the greatest leader, he still is better than ISIS. The reason ISIS has formed and gained a lot of power is because the US had receded troops from Iraq. Because they receded their troops, a power vacuum formed and as a result, a small group no one had heard about before rose to power. Now if we look at this example, taking Bashar al-Assad out of power would just lead to another power vacuum and could potentially lead to another rebel group like ISIS rise to power. Not only would this happen, but Russia has clearly stated that if any group, USA or not, forcibly removes Bashar al-Assad from power it would strike back with force. This would not be good for any nation and removing al-Assad from power would potentially lead to a world war. Now I'm not condoning the actions of al-Assad, the way he used chemical weapons on his own people is brutal and disgusting, but until we figure out a better solution, I'm sorry to say but Assad is our only option.
