He hasn’t learned anything from history. He never saw “Charlie Wilson’s war”, and never understood the rise of ISIS in Iraq, as a result of breaking up the Iraqi army, by Bush, and then leaving Iraq, another Bush decision, implemented by Obama, because Iraq wanted jurisdiction over US troops commiting any crimes in Iraq.
So, Trump the buffoon, repeats history, and allows Syria to be a sattelite of Russia, and an ally of Iran, right next to Israel.
