1) Syria under Assad was one of the major reasons why ISIS became an influential player in Iraq, when he allowed them to organize training camps within his territory along the border. The Frankenstein monster decided to repay them back in kind and evidently the result can be seen in front of us. This does not exclude the Saudi's, American's and Iranians who should also be blamed for the current climate in the Middle East.
2) The events in Syria would never have occurred in the first place, if Assad simply accepted political reform which he promised for a number of years. Instead he utilized the full might of his military machine to murder and torture innocent civilians, forcing units within the Syrian Army to rebel against the state.
3) The Russians have initiated a bombing campaign in Syria, however most of their intended targets are FSA and to be frankly honest with you they have barely touched ISIS. This particular case is a prime example where the Russian fighter plane was roaming a region held by FSA.
4) Every sovereign nation has the legal right under international law to protect its borders.
5) Bombing a country will never resolve the issue, until a political objective is set forward and this is severely lacking in all parties involved in Syria and Iraq.
