Instead of speaking of Hezbollah fighters, let us speak of Hezbollah criminals and Hezbollah terrorists. Same goes for, for example, hamas, islamic jihad, fatah, p.a., al quaida, islamic state in Iraq and the Levant/i.s./daesh and so on.
Even as far back as a year ago it was becoming apparent that Irans intentions in Syria were far from benevolent
Most of the indicators coming from statements from Hezbollah and RG officials boasting their power and control over Assad 'the Giraffe' in Syria and their ultimate aim to 'rid' Syria of all non Islamic forces including Russia
Where Russia has always been watchful of Irans ambitions and duplicity - only now does Assad realise that Iran-Hezbollah could pose an even bigger threat to his power than ISIS
