However, they didn´t ask President Assad if they may bomb in Syria. At least four airstrikes were conducted by the US airforce against ISIS in northern Aleppo. SOHR called this step "pragmatism". The US accused the Syrian airforce of bombing Al-Nusra, as if that would be bad thing. However, the SyAA chooses just the most remunerating targets, be it Nusra or ISIS. As long as the US isn´t bombing the Syrian army, however, each strike, and may it be ever so minor, is a good thing for the Syrians in the end. If the US is interested in fighting terrorism, it must now coordinate its strikes with Syria.
