Yes it is Putins fault he trusted Erdogan that's how things are when you think you are dealing with Men of honour, problem is he has done it more than once, as for Russian aircraft in Syria they had many not a few and Israel would not have attacked them if they had been used to destroy that convoy or there would have been a direct confrontation with Russia, as for HTS they were a cocktail of Turkish and Western backed head hacking terrorists including Al Nusra which had already changed it's name from Al Qaeda, there was no difference between those groups, they were a proxy army of the West to destroy Syrian resistance to the Zionists, now by all accounts they are being deployed by the Americans from Syrian prisons to Iraq where they will have a springboard to attack Iran.
