I have been wondering for years why these countries dont just take out the terrorists with planes!
Heck, they dont even need the latest fighters, they could use old crap from viet nam and wipe these murderous rag heads off the map.
Modern strike aircraft need a lot of ground logistics to operate. That is an extremely hard thing to keep up on when your country is small and in a civil war.
I suspect the Russians are flying the jets with Syrian paint.
