Israel have warned Syria that they will destroy all their air defences if they attack Israeli jets that fly over Syrian territory. So, if Syria has the temerity to defend itself against invading fighter planes, who ever they may be, Israel will destroy it’s S 200 and S 300. Good luck with that.
The parallel world that Israel insists is reality, appears to be predominant in their heads at the moment. They don’t seem to understand the word ‘defence’, either. Mr Netanyahu needs to realise that if his jets do not enter Syrian air space, there will be no need for Syria to defend against them. It’s not rocket science.
