ignorance? to claim downing a 6G limited swing wing aircraft with only AA-8s represents superiority of F-16? what a good statement, remember Assad kicked the ass of the west now he rules Syria and that is thanks Su-35s since the Russians also do strikes, and even downed most of the cruise missiles that did not damage Assad air force since it is still flying and L-39 is an advanced trainer but of 1970 vintage what a feat, where are the F-35s? over Syria?
WTF! Where was Su-35 when Israel was bombing Syria?
The only reason Assad is still in power is because America did not commit to removing him from power. It was Turkey and to some extent Israel that wanted Assad out. America did not really want to remove Assad. Just look at Saddam and Gaddafi (Gaddafi's removal was the brainchild of the French and Brits).
In Syria America was content to have bases to operate from. But Trump now wants total pullout to appease his puppet master Putin.
