I don't doubt that the Syrian army is ready to fight it out. I am unsure of how far they could take it with their present equipment. I am hoping that we don't repeat the Libyan scenario however. Much bigger piece to chew and for the same unclear objectives.
Article V, I don't see it. Even if Turkey was retaliated against in the case of a military intervention on Syria's air defenses.
Sometimes one has fight regardless of the state of their equipment. Once again I will use Serbia as an example (and put up a good fight).
So you think the Israeli planes were completely invisible? The jamming would have indicated that something was up.
No, but with everything else they probably couldn't even reach the plane. The other system were/are obsolete.
Or they didn't even switched their radars on.
Who knows, but fact is that they did not have any advanced air defense system at the time.
