Good response. A few more points:
1. Syria and Russia are fake enemies, framed with chemical warfare charges to cause problems for Trump.
2. The Syrians brought in Iran only to survive a rebellion that was supported by McCain and his allies in the USA. Now that they are no longer needed for this purpose, they will be resisted and gradually pushed back — with the help of Israel, and maybe also Russia.
3. Syria needs oil to rebuild, and it is theirs, not ours.
All three points correct.
