There are some minor differences here and there...
They are training those fighting ISIS
Actually, they are supporting those who are fighting the Assad government. There is a big difference. The FSA has never won a fight against the ISIS to date. On the other hand, thousands of them have defected to the ISIS.
they are supplying those fighting ISIS with intel and training
Just like the training given to the Iraqi Army? We already saw the results in Mosul.
and they are bombing ISIS on a regular basis.
Token strikes here and there will cause no damage to the ISIS.
