I think the last time the IDF has executed so many missions in this short a time was 1973 and look what happened to all the attackers then. Iran is kicking at a hornet's nest.
Iran or Syria would be fools to become directly involved. Which isn't to say it couldn't happen, wars don't proceed according to plan. As I noted on another thread, it's fair to say Jordan became involved in three wars, 48-67-73, not so much for stratigic reasons as to mollify an enraged population.
