This is costing the Russians virtually nothing as the expenditure is being taken directly from the training budget . Stockpiled ordnance is simply being dropped on jihadis in Syria rather than wooden targets in a Russian field and the live fire experience gained is invaluable . The vast majority of the stuff being dropped is cheap unguided munitions that were produced during the soviet era and stockpiled in huge quantities . Absolutely no shortage of it . The fuel to get it there costs them nothing either .
Once Allepo is secured ...and thats a certainty because theyre beseiged, have shot their bolt already and defences they spent years preparing are collapsing like dominos as we speak...there'll be a huge Syrian military force freed up to go on the offensive wherever it likes . Same with the besieged Eastern ghouta were huge numbers of Republican guard and Special forces are currently tied up . The outcomes of both sieges are certain government victory . They've those areas firmly locked down . There's no break out possible, no cavalry, no relief . After the failed attempt to lift the Allepo siege that was months in planning and preparation we now have major jihadi groups trading bitter accusations . With one even referring to the fate of their relief force as " a holocaust " .
And to add to jihadi woes as soon as Mosul is taken, which it will be, there'll also be a massive influx of Iraqi militias into Syria. Huge numbers . The manpower and firepower necessary to liquidate every last jihadi occupied position won't be a problem . Assads calculations are sound in that regard . He can take every inch back . Damascus is secure, Allepo is finally secure, latakias secure . He can do it . Methodically and slowly but it can be done . He has no obligation to capitulate to western and gulf demands whatsoever . The Syrian people would lynch him if he did after all the sacrifices they made to hold out this long .
Saw this article over at Sic Semper Tyrannis: Showdown in Aleppo, the author agrees with your own point a few pages ago when al-Nusra "broke the siege" of their forces in Eastern Allepo.
author seems a little naive in thinking the US would find being allied to Al-Qaeda/al-Nusra distasteful though, I've seen no evidence of that anywhere (apart from members of the Green Berets and the like, who don't like having to train them obviously).
