No, it wasn't. All Iran did was unnecessarily prolong the suffering of the majority Sunni population so they can prop up their criminal dictator ally Assad that brutalized our people for 50 years. If they didn't intervene when he was about to be toppled in the first couple years, we would not be so defenceless and fractured, we wouldn't have had so many hundreds of thousands of extra deaths and suffering in the past decade, and we might still even have our AD and ability to do something. Iran should've stayed in their own fucking borders and not intervened in our people's struggle for freedom, this is why millions of Muslims across the world who respected them before stopped supporting them. It was a stupid mistake to increase their power and control in the region and it cost them big time in the end.
