The battle of Aleppo was resumed after many failures that the Syrian rule should be blamed for and the US conditions are beyond expectations and they include: Halting the battles all over Syria , and introducing aid and delivering the Castello road to an unknown third party and for the Army to withdraw its heavy weapons and for the Syrian airforce to remain grounded after which the joint Russian / US military air strikes will start over Syria . This does not suit the forces of the Resistance who want to tighten the siege on Aleppo until the thugs surrender and evacuate the same way they evacuated in Darayya.
The conditions now are favorable to the Resistance, and the losses of the thugs are unimaginable in lives and in equipment and in spirit and they were defeated at all these levels . The planes were pounding their arsenals non stop and of course the Russian airforce was there because the Russian cannot but share in this achievement that they will have the right to claim and ask for their share in return.
This is to say that the forces of the Resistance are not ready now to sacrifice their achievements for the US to implement its agenda.
