Russia has assumed sponsorship of Iran and Iran will not be doing anything since that would lead directly to yet another Defcon 3 and even Russia would rather nuke Iran themselves than face that again.
Putin wants conflict. Anything that drives up the price of oil and makes Middle Eastern oil less accessible will create windfall profits for Russia. Europe is very vulnerable right now. Only France with its Nuclear Power Plants is in a position to challenge Iran (Russia's Puppet). Putin is not bringing May Day parades back as an effort to avoid raising defcon levels.
