Just to summarize what I've already said, the US (CIA) first orchestrated the Arab Spring protests in Syria and other middle east countries in an effort to stir up civil unrest, destabilize, and force out the governments of these countries. When that failed to unseat Syrian President Assad, the US formed ISIS and other smaller terrorist groups to fight the Syrian government. At the same time, the US started a massive effort to create a 'terrorist threat' cover story for military intervention in Syria. First, it fed 'terrorist threat' propaganda to the US public via the mainstream media (remember Jihadi John?). Secondly, it orchestrated false flag attacks in the US and Europe (San Bernardino, Paris, etc.) and fingered ISIS. Then, with it cover story established, it quietly built at least ten military bases in Syria, manned by 2000+ personnel and proceeded to attack Syria from within its own borders. Russia responded to an urgent request for help by Syrian President Assad, so Russia's military buildup in Syria was entirely lawful. Russia is an ally of Syria. The US most certainly is not. The US and/or Israel also launched mass drone attacks on the Russian airbase in Syria, causing damage to some aircraft. Russia largely destroys ISIS.
The US (or Israel) also orchestrated several false flag chemical weapon attacks on the Syrian people. The latest occurred in April 2018, which the US blamed on the Syrian government, despite a complete lack of evidence. Before an investigation could be started, President Trump promptly launched a cruise missile attack on Syrian infrastructure. The Syrian conflict and the entire Middle East refugee crisis is Uncle Sam's handiwork. Syrian President Assad has the overwhelming support of the Syrian populace. They know what the US has done to them.
Of course, the US military-industrial complex propaganda machine has worked it's magic on the majority of the American populace. Your comments are a perfect reflection of this.
