The invincible F-35 cannot fly far enough to do anything - it is so range limited it would have to be positioned in Syria to be effective if it could carry any bomb load which amounted to anything.
There are no known drones which could pull off anything bomb-wise anywhere in Syria with out being shot down within seconds of crossing the Syrian boarder.
Thanks for sharing your ignorance with us. Incirlik Air Base to Aleppo is about 130 miles - 260 round trip. Combat Radius of the 35-A is 625 nautical miles.
You should probably rely on things other than the Boeing talking points. The bigger question, which you missed, is whether the 35 is combat ready. And the answer to that is 'probably not'.
