depends. iran very much does not want a war right now, they aren't ready. it would make sense for israel to hold off for the time being; let iran have their propaganda victory and let things cool off. it would open up breathing room to work down hezbollah / hammas and eliminate iranian proxies, putting them ahead in the long game. this of course allows iran to gain strength for a future confrontation but the united states is always going to major off shore balancer. that being said, should america commit to an offensive against iran, israel could have a perfect opportunity to wage a preventative war against a major competitor.
