Syrian army has been corrupt and have stolen money from their people and could not defend their country against al-Nusra Front or Al Qaeda forces.
Persian troops fought very hard and defeated these al-Nusra Front or Al Qaeda forces in the past and were asked by Assad to leave and they left.
Persia aslked Russia to help and they came and help.
Russia told Assad he needs to reengineer his army to be a professional army and he said no. Assad asked Russia to leave.
We hate these groups because they killed a lot of innocent people in 9-11 and we would never forget that.
Current Syrian government is our enemy and our government must not give our tax money to them.
