Do you have evidence, polls, statistics to support your contention that "most impartial observers" believe that America is the belligerent in this incident?

Or did you just pull that one out of your imagination?

Please share any such evidence, polls, statistics with us or we'll have to conclude that you don't speak for "most impartial observers", just for yourself.

As for "what gives the USA, Israel, Canada, Turkey the right to be in Syrian airspace accept being belligerent?", someone has to attempt to stop the mass slaughter of innocent Syrian civilians by the militaries of Assad and Putin.
