Ok then what comes after Assad? Who rules the nation? The rebels? Which group HTS aka Al Nusra which is the strongest rebel group right now aka Al Qaeda in Syria? Ahrar al Sham whose spokesman said that they admire the way the Taliban rules Afghanistan? Jaish al Fateh which rules Idlib province and uses sharia law to rule? What will happen to the Alawites, christians, and Druze who support Assad because there is actual Jihadist and Islamist groups who want them dead? What of the Kurds will they get their own land if you do that Turkey get pissed. If you dont you have an army of 100k heavily arme dKurds that fought the rebels since 2012. This line of thinking is what led to the epic fail in Libya and Iraq. Get rid of a strongman and then there is chaos. Syria has so many armed factions that not one man can rule. Hell Assad doesn't run all of Syria. If you destroy the Baathist govt you destroy Syria because they employed the most people and provide services. Assad controls all the major cities. If you take him out then what happens to Homs,Hama,Aleppo, Damascus etc? If you get rid of Assad there will be more chaos. Intervention with no plan will lead to failure. Look at Libya and Iraq. You have no clue what is actually going on with the game of thrones that is Syria. It is not black and white.
