In the aftermath of the assassination of Hamas leader Ismail Haniyeh, Iran finds itself at a crucial juncture as it grapples with how to retaliate against Israel without escalating tensions in the region further. Despite public statements vowing a "tough" reprisal, behind closed doors, Iranian officials are urging caution to their armed proxies, signaling a desire to avoid an all-out war.

Iran's first direct attack on Israel in April, where over 300 drones and missiles were unleashed in response to an Israeli strike on an Iranian diplomatic facility in Syria, effectively erased long-standing red lines and heightened the risk of a full-scale conflict. However, this time around, Iran faces internal political uncertainty and is less certain of Israeli restraint.

Israeli officials, citing conversations with security officials, have indicated that another direct attack from Iran could be imminent. Preparations have been made by Israel, with the deployment of the USS Georgia, a guided-missile submarine, and the hastened journey of the USS Abraham Lincoln aircraft carrier strike group to the region, but tensions remain high as the region eagerly awaits Iran's response.

According to individuals familiar with Tehran's communications, Iran is treading cautiously, intending to keep any retaliation limited as they seek to prevent the war from escalating. Concerns have been raised about the possibility of Israel and the United States using a full-scale conflict as a pretext to undermine Iran's nuclear program.

Aliasghar Shafieian, campaign media adviser to newly elected Iranian President Masoud Pezeshkian, stated that Iran's response would be of a similar nature and level as the assassination of Haniyeh. While the United States emphasizes de-escalation and support for its ally's defenses, Iran's allies in Iraq and Syria have been put on high alert, potentially planning attacks on U.S. bases in those countries.

The delay in Iran's response following Haniyeh's assassination is believed to be a strategic move aimed at keeping Israeli authorities anxious. However, this delay also sheds light on Iran's anxieties during a fragile political transition, with Pezeshkian being the country's first reformist president in nearly two decades.

A regional war could further isolate Iran and exacerbate its economic crisis, as the value of the Iranian rial continues to plummet. Pezeshkian, who campaigned on greater engagement with the West, is currently focused on managing the situation and engaging in diplomatic conversations with foreign counterparts.

As tensions persist in the Israel-Gaza conflict, the repercussions are spilling into the broader Middle East region. The assassination of Ismail Haniyeh has added another layer of complexity, as Iran carefully considers its response to Israel's action, seeking to strike a delicate balance while averting a full-blown confrontation.

It remains to be seen how Iran will eventually respond, with analysts noting that forthcoming actions from Iranian intelligence could target soft Israeli targets overseas, such as embassies. The region remains on high alert, awaiting Iran's next move, as the situation continues to evolve.
