rebelled and the Rebels ( who are good ) started winning ( Hurrah!).
But then some of the rebels turned a bit nasty and are now called Islamic
State ( who are definitely bad!) and some continued to support democracy (who are still good.)
So the Americans ( who are good ) started bombing Islamic State ( who are
bad ) and giving arms to the Syrian Rebels ( who are good ) so they could
fight Assad ( who is still bad ) which was good.
