Not a bad rundown but it's heavily biased against Assad. Syrian Spring was an American/Saudi orchestrated astroturf movement and there are some doubts about how "unarmed" those "peaceful protesters" were and how (even with some defections) they got armed so quickly. Also, the video glosses over the fact that among those "poor rebels", al-Qaeda has been receiving the bulk of "Lavrov's breadbaskets" - the commentator is lumping them with all those supposed peaceful, "moderate" rebels. The same guys who weren't above using chemical weapons themselves and even today, when they saw parachuting Russian pilots, they fired at them, which is a war crime. Also they've been engaged in killing civilians, ethnic cleansing and even teaming up with al-Nusra and ISIS when it was convenient for them.
If you go further back, Syrian Spring was astroturfed in the background of the Russians actively working to topple the USD as the sole world trade currency. The US also had a strategic interest in taking away Russia's only Mediterranean naval base, the same way they astroturfed the rebellion in Ukraine to take Sevastopol away from the Russians. In the Islamic world, the spat has more to do with the proposed pipeline that's supposed to go through Syria and whether it will carry Gulf Arab oil/gas or Iranian oil/gas. So this wasn't a popular uprising for democratic values by any means. People who financed it will put you in jail for tearing up the king's picture and will chop off your head for renouncing Islam. They are our friends and allies
Another interesting bit is that the Kurds up north are actually not fighting Assad at all. They are focusing their battles on ISIS. Assad is the only truly secular leader in the region. Why do you think the Christians and other minorities are behind him in this fight?
I was born in Europe, spent most of my life in Canada, so I don't have a dog in this fight but the author of this video drank a little too much MSM Kool Aid, so I had to point out a few things that he didn't.
Edit, important bit of info:
Take any quotes of the Syrian Observatory for Human Rights and Syrian Network for Human Rights with a BIG lump of salt!!! SOHR is a one-man operation, funded by the EU and the British government (admitted in a NY Times interview). It's a fabric shop owner in Coventry, chatting on the phone with his insurgent buddies and relaying their propaganda. For example, if the dead guy didn't wear a Syrian Arab Army uniform, he's a "civilian casualty," even if he's an Al Nusra Front fighter or an ISIS head-chopper. SNHR is exactly the same, but based in a different part of Great Britain and it's two guys, not one (maybe they should be called the Syrian
Line for Human Rights
) Both sources are highly biased, so I only use them for confirmation of Russian/Syrian propaganda (rare, but it happens - when the truth is impossible to hide).
