Streikov: "... (I remind you that Turkey is now strenuous friends with the main opponents of Iran — Israel)...
IMO Iran's main opponent isn't so much Israel as Saudi. The two have been jostling to see which becomes regional hegemon for decades at least. Israel is a convenient enemy (neither Suni nor Shia - arguably the root of the Iranian/Saudi conflict - plus Israel is easy to hate based on their treatment of CO-religionist Palestinians, who are a cause celebre in the region).
Disclaimer: I've lived in the region. I found that if I needed help, the person most likely to drop whatever he was doing and come help was a Palestinian. I felt safer around checked headdresses (easy way to spot Palestinians) than otherwise, which colors my attitudes towards Israel.
