Absolutely ridiculous statement. Hamas caused 10/7 and Iran is the leading supporter of Hamas in terms of funds and weapons.
Iran's Islamic Revolutionary Guard Corps (IRGC) worked with Hamas to plan its 7 October 2023 surprise attack on southern Israel and gave the green light for Hamas to launch the assault on a meeting in Beirut on 2 October. In the Hamas-led attack, Palestinian militants killed 1,200 Israelis, primarily civilians, and took around 200 Israeli civilians and soldiers hostage.[24] In the weeks leading up to the attack, some 500 fighters from Hamas and Palestinian Islamic Jihad received training in Iran, under the guidance of the IRGC Quds Force.[25]
According to The Washington Post, the attack occurred "with key support from [Iran] who provided military training and logistical help as well as tens of millions of dollars for weapons."[5] According to The New York Times, Internal documents indicate that Hamas sought to persuade Iran and Hezbollah to participate in its attacks.[26][27] The group deferred the assault from an initial 2022 plan, aiming to secure regional backing. Although Iran and Hezbollah offered support, they were unprepared for direct involvement, prompting Hamas to proceed independently.[26][27]
So second down the list. If you are lowballing Iranian involvement.
