The mess in Syria was created and fomented by the West. Russia, the Syrian government, and the Syrian people are all on the same side.
The mess in Iraq was also created and fomented by the West.
The idea that the West is abandoning Syria by reducing its support for terrorist extremists (that the West created) who seek to impose a sharia law theocracy, and who kidnap, torture, behead, and execute by other means anyone who does not conform to their religious extremism is equivalent to saying that the West was abandoning the Jews by opposing the Nazis in WW2.
