not 100% sure this wasn’t disinformation to split Iran’s D.
Israel may have indeed wanted to use Azerbaijan as disinformation to split Iran’s D. If they wanted a disinfomation campaign to be effective however, the Israelis would have sent information through a back channel to warn the Iranians while sending other agents with the message that an Israeli Azerbaijani alliance was bogus. Now, Iran will make certain that Azerbaijan will not have an Israeli set foot on their territory and plan their defenses accordingly.
