absolutely correct umitatl, a good response to Sunfish's whitewashing of NATO from its relation to ISIS/IS or wharever f#@$.
ISIS has emerged out of nowhere in February 2014 just because the battle for Syria got stuck/stalemated, in concert with Ukraine "crises" directed by Victoria Nuland. A "casus bellum" was required to continue the battle in a more covert manner hence ISIS's emergence to provide that cover.
This attack together with the metrojet's attack's beg's for a response from Russia. And so they will deliver this , see history.
A possible scenario I can think of is 1 response to Turkish airforce/ground troops and 1 to the participating ME airliners (including ISisrael).
Certainly very interesting times ahead. Poking a bear or even a cat for that matter is not a good idea. The reaction will be in direct proportion to the size of the animal.
