LUHE:
in arriving at your views, have you read anything on this topic from official sources - not much. So?
Well, yet you know exactly what is happening and what should be done...
Your talking points are not well aligned with the facts but do align with the pro-kremlin misinformation about Syria. I would simply invite you to read reports on what is happening but here is a brief summary:
Syria has 4 major factions: Assad, ISIS, Islamic rebels and Western rebels (Kurds, etc.).
The western oriented rebels were backed by an international alliance spearheaded by USA; they are the best we come to "good guys" in Syria.
In 2015 Putin announced(!) the war in Syria was between ISIS and Assad and things were going really badly (in reality, it was going badly for Assad, less badly for the rebels who were fighting ISIS), and now it was time for an international alliance to form and defeat ISIS.
So he joined efforts with the international alliance and began bombing ISIS. Nah. Just kidding.
He began to bomb the shit out of the internationally backed rebels and other enemies of Assad under the pretext he was bombing ISIS. That was only in a few cases true as was confirmed by comparing claimed ISIS targets with what was actually bombed.
In addition to military targets, hospitals, bakeries, water treatment plants, grain silos, mosques, and cities were bombed. Russian cluster munition was used in Syria (that's a warcrime) and images surfaced of Russian fighter planes with said cluster munition attached. Might be a total coincidence.
In 2016 Putin announced, "mission accomplished". At this point, the Russian campaign had been successful in weakening the western-backed rebels and helping Assad but had not weakened ISIS significantly. By hitting civilian targets (water treatment plants, hospitals, etc) and complicated the conflict it had deepened the humanitarian crisis and created more refugees.
During this campaign and after the following propaganda points were repeated again and again:
- The choice is between ISIS and Assad
- There is no meaningful alternative
- Putin intervened because nothing was being done
- Putin has only aimed at ISIS/terrorist targets
- Putin has not used cluster munition
- Putin's bombing campaign significantly weakened ISIS
I invite you to read about the conflict before you repeat the above points.
