Russians are the biggest betrayers in the ME. The Russian power structure is fully infiltrated by the Zionists. Most of the oligarchs in Russia are Zionists.
Russia will backstab Iran and any others in the ME in preference to Israel. Every single defense system sold by them is already compromised because of Russia's relationship with Israel.
Iran is in this all alone. They need to preserve their assets and bet on the long haul. They have that experience from the Iran-Iraq war. They will certainly take a lot more damage but their resilience will carry the day. Trump is not in this war for the long term and the American public is in no mood for a war that is being fought only for Israel's sake.
