Is Israel on a collision course with Russia?

The whole thing is cowardly and unthinkable - but Syria is getting the S-300s. It is reported that Israel relayed the wrong coordinates to Russia in order to cover itself with the Russian military aircraft as a shield, to protect itself from the Syrian missile defense systems. This will not happen again as the Russian S-300 is able to identify a potential Russian target.

Yet, who will be held to account for the unnecessary deaths of 15 Russian servicemen? What on earth is Israel up to?
