I don't believe that to be the case. The Arab nations threatened by Iran need a strong partner to counter the dangerous ambitions of the mullahs. Since the US can no longer be trusted, Israel is the most logical choice for a strong regional alliance.
Iran is a mortal threat to them. Israel may be the only power with the will and the power to stop Iran. I look for more Arab countries to sign up with Israel.
Israel is surely willing to put a stop to Iran...but are they capable of doing so? My guess is that short of using nukes themselves they’re not.
