Trump is an existential threat to Iran. Iran is in a regional cold[0] war with Israel. Israel’s ability to wage this war is largely dependent on US support; both in terms of raw military assistance, and in the US providing diplomatic and economic cover for Israel.

While the US had not applied nearly as much moderating pressure on Israel as I would have liked, it has still provided some. Israeli prime minister Netenyahu, in contrast, has been angling for a direct confrontation with Iran for decades now. Given the past 11 months, there are serious forces, both in Israeli politics, Iranian politics, and the inertia of war, pushing in that direction.

Trump is aligned with Netenyahu on this point, and would push him towards a direct confrontation with Iran. By all indications, Harris is not. This dynamic was made clear to Iran when the Democratic administration signed the Iran nuclear deal (against Israeli opposition), from which the US under Trump proceeded to unilaterally withdraw from.

[0] Cold might be a bit of an understatement after the last 11 months. However, apart from a brief tit-for-tat exchange, the fighting has stayed confined to Israel and Iranian proxies.

Because tensions between Hezbollah and Israel have been steadily rising since October 7th because of Hzebollah’s objection to how Israel is acting in Gaza. To be clear, prior to October 7th, tensions were already high enough that they would regularly lob bombs at each other. Today’s “escalated” tensions include northern Israel being evacuated due to threats from Hezbolla’s rocket attacks.

At this point, it is clear that the options available to Israel are to either withdraw from Gaza and hope Hezbolla stands down, or end up in a full war with Hezbolla. Historians will say that the war with Hezbolla started months ago, and this was just one attack among many.
