Iran also sat on its butt and did nothing but display to Israel Iran's capability of overcoming the Iron Dome air defense system. By doing so without knocking out Israel, Iran warned Israel of Israel's vulnerability and pissed away its strategic advantage. Putin by denying Iran the Russian S-400 air defense system, has permitted Israel to continue to assassinate from the air Hezbollah's leaders in Iran. Putin's failure to protect an ally has strengthened the US/Israeli position in the Middle East and weakened Russia's.
