Iran is likely now planning for its next attack in order to establish deterrence with Israel while still avoiding a large-scale war. One of the most dangerous but increasingly likely scenarios is that Iran and the Axis of Resistance launch a combined, large-scale drone and missile attack that incorporates lessons from the April 2024 attack. Iranian leaders, in this scenario, could increase the volume of projectiles fired at Israel by launching more from Iran, from the surrounding countries, or both. Hezbollah, the Houthis, and Iranian-backed militias in Iraq and Syria could launch simultaneous attacks to further strain Israeli air defenses as well. Drones and missiles launched from Iraq, Lebanon, and Syria would be much harder to intercept than the ones from Iran given the shorter distances and flight times to Israel. US and Israeli forces would have significantly less time to intercept those projectiles. It would take Hezbollah drones around 15 minutes to reach Haifa and around 40 minutes flying on direct paths to reach Tel Aviv, for instance (although many drones will likely fly indirect and longer routes).[10] Iran could alternatively exploit the short flight times to concentrate a smaller volume of fire against a single target in Israel rather than against two. Shorter flight times for the drones could make it easier to coordinate them with ballistic missiles fired from Iran, whose flight times are generally less than 10 minutes. If Iran and its partners and proxies can concentrate drones and missiles on Israeli targets simultaneously, they may have reason to expect that the distractions caused by the one can facilitate penetration by the other.
Iran and the Axis of Resistance will also benefit from the fact that they have probed Israeli air defenses extensively since April 2024 and thus learned how to attack them more effectively. Hezbollah and the Houthis have both conducted attacks that have successfully bypassed Israeli air defenses since April 2024. The most notable example was the Houthi drone attack on Tel Aviv on July 19 that killed an Israeli and injured four others.[11] Israeli air defenses have similarly struggled to intercept Hezbollah drones in recent months because of the short flight time and mountainous terrain.[12] The success that Israel and its allies and partners had in defeating the April 2024 strike should not be cause for complacency in the face of a new attack. But Israel and its supporters have multiple systems to engage various kinds of targets and are aware of the capabilities Hezbollah's drones have shown, so neither is there cause for pessimism.
Iran could inadvertently trigger an expanded conflict with Israel and even the United States if Iran launches an attack along the lines described here. Launching hundreds of projectiles is inherently risky, particularly given the failure rate that Iranian missiles have shown.[13] Technical errors could cause severe collateral damage, as demonstrated by the recent Hezbollah attack that killed 12 Israeli children in the Golan Heights.[14] This risk is higher given reports that Iran is planning to target locations near Haifa and Tel Aviv.[15] Both cities are far more populated than the two remote locations that Iran targeted in April 2024. The risk of civilian casualties is thus very high even if Iran does not mean to strike civilian targets around Haifa and Tel Aviv. Iran could trigger an expanded war if it kills Israeli civilians or inflicts severe damage—regardless of whether Iran intends to avoid an overt war. It may not be immediately obvious to Israeli leaders that a large strike aimed at one or two targets is not, in fact, aimed at a much wider target set, moreover. Drones have long ranges and often fly far beyond their targets before turning to hit them from the rear. The risk of miscalculation in a strike such as the one described is very high.
The Israeli airstrike targeting Fuad Shukr in Beirut on July 30 also killed an Iranian Islamic Revolutionary Guards Corps (IRGC) Quds Force officer, Milad Beydi.[27] IRGC Commander Major General Hossein Salami released a statement mourning the killing of Beydi and blaming Israel for his death.[28] Salami described Beydi as one of the Iranian military advisers in Lebanon and Syria.
The Israel Defense Forces (IDF) confirmed that it killed Hamas’ top military commander, Mohammad Deif, in an airstrike in the al Mawasi humanitarian zone on July 13.[29] The IDF confirmed that the airstrike killed Deif in a statement on August 1.[30] An Israeli military correspondent reported that the IDF received definitive intelligence that confirmed Deif’s death in the hours prior to the announcement.[31] The al Qassem Brigades—Hamas‘ military wing—has not released a statement acknowledging the IDF statement as of this writing.

Iran Update, August 2, 2024
The following indicators would support the hypothesis that Iranian-backed militias are preparing to attack US forces in eastern Syria.
Iranian-backed militias massing additional forces in or around eastern Syria
Iranian-backed militias leaving their stations in western Iraq or other parts of Syria
Iranian or Iranian-backed militia leaders meeting in eastern Syria
Iranian-backed militias flying ISR drones around US forces in eastern Syria
Iranian-backed militias in eastern Syria conducting exercises simulating attacks on US forces
Iranian or Iranian-backed militia leaders in eastern Syria taking heightened security precautions
Iranian or Iranian-backed sources signaling publicly the possibility of intensified conflict in eastern Syria
Iranian-backed militias rapidly increasing the dissemination of anti-US disinformation in eastern Syria
CTP-ISW has not independently observed confirmation of any of these indicators, and many of them are unlikely to be observable in the open-source environment.
Anonymous Western intelligence sources told Sky News Arabia that Iran and Lebanese Hezbollah may attack Israel on the Jewish holiday Tisha B’Av on August 12-13 in retaliation for Israel killing Ismail Haniyeh.[8] Tisha B’Av commemorates the destruction of the First and Second Temples and is widely considered a day of sadness and tragedy. An Iranian-Hezbollah attack on this date would come about 12-13 days after Israel killed Haniyeh on July 31. Iran similarly waited 13 days before retaliating against Israel in April 2024 for killing senior IRGC commander Brigadier General Mohammad Reza Zahedi.[9]
