Iran had been conditioned to think that the status quo would remain and they would not have to face retribution from the US or the west for their terrorist activities in the region. Trump broke the status quo by taking out their top terrorist for his actions that have killed or maimed thousands of Americans. Orchestrating an attack on the US Embassy in Iraq, which is American soil, could not go unpunished like Benghazi. Iran is now aware that the US can and will kill anyone who attacks America. Soleimani’s replacement is unlikely to be so bold as his predecessor.
