As a collective security organization, he would seem to have a point (assuming that Azerbaijan attacked Armenia proper, not Nagorno Karabakh, which isn't recognized by anyone and which isn't a CSTO member). But would CSTO member countries (including Russia, Belarus, and all the 'stans except Turkmenistan) actually come to Armenia's aid? It seems hard to fathom, and Azerbaijani political scientist Rasim Musabeyov agrees:

“The statements of the director of the CSTO Armenian office Nver Torosyan spread by Armenian mass media are absurd”, political scientist Rasim Musabeyov said....

Thus, Armenia will get no support from CSTO. He may have hinted at Russia, but in this case Moscow says officially that it recognizes the territorial integrity of Azerbaijan”, said the analyst.
