The pagers do give Israel a certain veneer of plausible deniability that they wouldn’t otherwise have if they had used more traditional bombing methods.
Literally everybody in the entire world believes Israel is responsible for this. An Mk-82 bomb dropped from a bomber would have more deniability. This was a joke about Israel's tactical signature back when James Mickens included it in a Usenix Security throwaway paragraph back in 2014. There is absolutely no deniability here, unless someone very powerful is deliberately trying to frame Israel (which is not what is happening).
