The main reason for the Russian decision to use Hamedan is not only a technical one. The fact that the Iranians have now publicly made this base available to Russia indicates a deepening of the strategic collaboration between these two countries and a stronger Russian commitment to the defense of Syria against the foreign invaders, something which Tehran had been wanting the Russians to do for a long while. The Iranians have always been dubious, to say the least, about the Russian peace plans and now that the Russians are gradually coming to admit that Daesh did use this time to regroup, rearm and reorganize, the Russian move to Hamedan indicates that the Kremlin is serious about hitting Daesh as hard as need be to protect Syria from the Takfiri invasion.
