As the highest-ranking leader of the al-Qassam Brigades, Deif was involved in orchestrating the [[2023 Hamas-led attack on Israel|surprise attack on Israel]] that commenced the [[Gaza war]], which, according to a source close to Hamas, he began planning in the lead up to the 2021 Israel–Palestine crisis, motivated by scenes of Israeli forces storming [[Al-Aqsa|al-Aqsa Mosque]] during [[Ramadan]].<ref name="reuters20231010" /> According to [[France 24]], he was the mastermind behind the attack on 7 October.<ref name="france24-20231103">{{Cite web |date=3 November 2023 |title=Who's who: Top Hamas leaders on Israel's radar |first=Marc |last=Daou |url=https://www.france24.com/en/middle-east/20231103-most-wanted-the-hamas-leaders-on-israel-s-radar |access-date=17 December 2023 |publisher=France 24 |language=en |archive-date=14 December 2023 |archive-url=https://web.archive.org/web/20231214032845/https://www.france24.com/en/middle-east/20231103-most-wanted-the-hamas-leaders-on-israel-s-radar |url-status=live}}</ref> The decision to launch the attack was taken jointly by Deif and [[Yahya Sinwar]], the leader of Hamas in the Gaza Strip.<ref>{{Cite web |last=Sanz |first=Juan Carlos |date=18 October 2023 |title=Mohamed Deif and Yahya Sinwar, the masterminds of the Hamas attack who top Israel's most wanted list |url=https://english.elpais.com/international/2023-10-18/mohamed-deif-and-yahya-sinwar-the-masterminds-of-the-hamas-attack-who-top-israels-most-wanted-list.html |access-date=19 November 2023 |website=EL PAÍS English |language=en-us |archive-date=19 November 2023 |archive-url=https://web.archive.org/web/20231119160901/https://english.elpais.com/international/2023-10-18/mohamed-deif-and-yahya-sinwar-the-masterminds-of-the-hamas-attack-who-top-israels-most-wanted-list.html |url-status=live}}</ref><ref name="lemonde20231011">{{Cite news |date=11 October 2023 |title=Mohammed Deif, Hamas's shadow strategist |language=en |work=Le Monde |first=Hélène |last=Sallon |url=https://www.lemonde.fr/en/international/article/2023/10/11/mohammed-deif-hamas-s-shadow-strategist_6165256_4.html |access-date=19 November 2023 |archive-date=19 November 2023 |archive-url=https://web.archive.org/web/20231119165414/https://www.lemonde.fr/en/international/article/2023/10/11/mohammed-deif-hamas-s-shadow-strategist_6165256_4.html |url-status=live}}</ref>

After the attack, a [[Reuters]] report stated that over the previous two years, Deif deceived Israel into believing Hamas was not interested in another round of conflict.<ref name="reuters20231010" /><ref>{{Cite web |date=11 October 2023 |title=How Mastermind Mohammed Deif Planned Hamas' Attack on Israel From the Shadows |url=https://www.timesnownews.com/world/how-mastermind-mohammed-deif-planned-hamas-attack-on-israel-from-the-shadows-article-104343052 |access-date=6 November 2023 |website=TimesNow |language=en |archive-date=6 November 2023 |archive-url=https://web.archive.org/web/20231106184911/https://www.timesnownews.com/world/how-mastermind-mohammed-deif-planned-hamas-attack-on-israel-from-the-shadows-article-104343052 |url-status=live}}</ref> This deception campaign involved a decision not to participate in the clashes between Israel and the [[Palestinian Islamic Jihad]] in [[2022 Gaza–Israel clashes|August 2022]] and [[May 2023 Gaza–Israel clashes|May 2023]], putting Israel under the impression that Hamas "was not ready for a fight" and could be contained by providing economic incentives to Gazan workers.<ref>{{Cite news |last1=Nakhoul |first1=Samia |last2=Saul |first2=Jonathan |date=10 October 2023 |title=How Hamas duped Israel as it planned devastating attack |language=en |work=Reuters |url=https://www.reuters.com/world/middle-east/how-israel-was-duped-hamas-planned-devastating-assault-2023-10-08/ |access-date=6 November 2023 |archive-date=9 October 2023 |archive-url=https://web.archive.org/web/20231009020650/https://www.reuters.com/world/middle-east/how-israel-was-duped-hamas-planned-devastating-assault-2023-10-08/ |url-status=live}}</ref>

On the day of the attack, Deif gave an audio address, his first since 2021, justifying it as a response to the "[[2022 Al-Aqsa clashes|desecration]]" of the [[al-Aqsa Mosque]] and the killing and wounding of hundreds of Palestinians in 2023.<ref name="sky20231010" /><ref name="france24-20231019">{{Cite web |date=19 October 2023 |title=Hamas masterminds key targets of Israel's 'dead man walking' threats |url=https://www.france24.com/en/live-news/20231019-hamas-masterminds-key-targets-of-israel-s-dead-man-walking-threats |access-date=19 November 2023 |website=France 24 |language=en |archive-date=19 November 2023 |archive-url=https://web.archive.org/web/20231119160900/https://www.france24.com/en/live-news/20231019-hamas-masterminds-key-targets-of-israel-s-dead-man-walking-threats |url-status=live}}</ref><ref name="TOI1" /> He called on Palestinians and Arab Israelis to "expel the occupiers and demolish the walls".<ref name="TOI1">{{cite news |url=https://www.timesofisrael.com/hamas-commander-says-attacks-are-in-defense-of-al-aqsa-claims-5000-missiles-fired |title=Hamas commander says attacks are in defense of Al-Aqsa, claims 5,000 missiles fired |first=Gianluca|last=Pacchiani|access-date=7 October 2023 |date=7 October 2023 |work=[[The Times of Israel]]|archive-date=7 October 2023 |archive-url=https://web.archive.org/web/20231007094309/https://www.timesofisrael.com/hamas-commander-says-attacks-are-in-defense-of-al-aqsa-claims-5000-missiles-fired/ |url-status=live}}</ref><ref>{{cite web|url=https://www.nytimes.com/article/israel-gaza-hamas-what-we-know.html|title=What We Know About the Hamas Attack and Israel's Response |first1=Ephrat |last1=Livni |first2=Gaya |last2=Gupta|work=The New York Times|date=7 October 2023|accessdate=7 October 2023|archive-date=8 October 2023|archive-url=https://web.archive.org/web/20231008143358/https://www.nytimes.com/article/israel-gaza-hamas-what-we-know.html|url-status=live}}</ref> Announcing the start of "[[Operation Al-Aqsa Storm]]," Deif said that "In light of the continuing crimes against our people, in light of the orgy of occupation and its denial of international laws and resolutions, and in light of [[United States support for Israel in the Gaza war|American]] and western support, we've decided to put an end to all this so that the enemy understands that he can no longer revel without being held to account."<ref name="reuters20231010" /><ref name="ft20231008" />

On 20 May 2024, a request for an arrest warrant against Deif and four other Palestinian and Israeli leaders was filed by the [[Prosecutor of the International Criminal Court]] (ICC) on several counts of [[war crime]]s and [[crimes against humanity]], as part of [[International Criminal Court investigation in Palestine|its investigation in Palestine]].<ref name="ICC_arrest_warrants_Palestine">{{Cite web |last=Khan |first=Karim A.A |date=20 May 2024 |title=Statement of ICC Prosecutor Karim A.A.
