War in Syria has been going on for four years now. ISIS is involved in this war and it is being used by coalition governments as an asset.
ISIS is being used as an excuse for others to pursue their own political agenda. Turkey is the latest to start its war against terrorists.
In case Syria asks Moscow for help, Russia will deploy the paratroopers. According to reports, Russia is ready to support Syria in countering terrorists by providing military units.
Based on the statement of Airborne Troops Colonel-General Vladimir Shamanov, if it is needed, they will respond to orders set by the country’s leadership. This assistance is logical because Russia and Syria maintain good relations.
Moreover, if the US can protect its interests by sending military units, so can Russia send in a few airborne troops.
In conclusion, everything boils down to protecting political interests.
