Sorry, but you seem to have as much 'understanding' for what is the IRGC/Hezbollah-conglomerate doing in Syria - as Putin, the Israeli government, and all the possible other foreign governments and their useless intelligence services. Combined.
The IRGC is not preparing an attack on Israel from Syria 'tomorrow in the morning'.
On basis of exepriences with the build-up of Hezbollan in Lebanon, it's working 'in generations'. Or, in words of one of top IRGC ideologists (and that on occassion of opening another Shi'a religious centre in Latakia some 4-5 years ago): 'We do not need you: we need your children and grandchildren'.
For the start, they're providing them with free elementary schooling at such centres. Older teenagers are attracted with stipends for studies in Iran - highly attractive, for (thanks to Assadists and 10+ years of war) Syrians are piss-poor.
What does that mean? They're growing entirely new generations of youngsters - Syrians, and grandchildren of Palestinian refugees - indoctrinated with the Twelver Shi'a. More loyal to Tehran than Hezbollah ever could dream about getting. And available in dozens-, then hundreds of thousands.
No. Not tomorrow. In 5, 10, 15 years - or longer, as necessary.
