Iran is not fighting 'everyone' if you imply Arab countries. Bases in Arab countries or infra in Arab countries which are helping the attacks on Iran. But that's essentially fighting only America and Israel, and maybe a few Western countries, if you think about it. Arab countries are not launching missiles on Iran and they probably will not.
Related to his, I think Pakistan and Turkey are playing their roles to convey messages between Iran and Arab countries to not go to open wars against each other.
