Wrong again dipshit.
First, the US had no compelling interest in Syria beyond taking down ISIS, which is exactly what Trump did.
Second, when Assad ignored Trump's warning, he bombed the shit out of Shayrat Airbase with Tomahawk missiles. It was Putin that withdrew the Russian fleet from Tartus when Trump told him what was about to happen.
And when Russian troops attacked US forces in eastern Syria, they got their asses kicked, and Putin could do nothing about it.
Trump is not afraid of Putin, and never was. Both Trump and Putin were fully aware that the Dem narrative was a political fabrication. Neither leader wants a war, and that is just a basic common sense realization that you cannot grasp.
Your TDS and Putin fixation have rotted your brain. Go scream at the lake.
