Israel against Iran: regional conflict scenarios in 2024
Four scenarios capture the main dynamics of conflict between Israel and the US on the one hand, and Iran and the axis of resistance on the other. They are: ‘a fight for the status quo’, ‘shifting red lines’, ‘limited war’ and ‘total war’. The first two scenarios amount to muddling through under the permanent threat of escalation, which could happen due to unintended yet possibly catastrophic incidents. The more warlike scenarios signify a shift to high-intensity war across large parts, or all, of the region. As 7 October 2023 created tighter linkages between the Israeli occupation of the Palestinian territories and the regional conflict between Israel/US and Iran, the violent dynamics of either issue can trigger each scenario. Meanwhile, scenario pathways lie so close to each other that tipping points can swiftly transform one scenario into another. Together, the scenarios point to the need to develop conflict prevention measures between Israel, the US and Iran – such as hotlines, protocols that spell out red lines and tolerable action/reaction bandwidths or even demilitarised zones – between now and the US presidential elections in November.
The core strategic objectives of the conflict parties suggest that progress is possible. Israel seeks to restore the security of its northern border without an all-out war against Hezbollah or Iran. It also intends to continue occupation. It does not care enough about normalisation with Saudi Arabia to discontinue annexation, which means it will not alter the regional security order to an extent that could truly threaten Iran. Tehran, in turn, seeks good relations with the Persian Gulf states, recognition as a regional power and the isolation of Israel. The US wishes to uphold Israel’s security by reducing the risk of Hamas, Hezbollah and Iran, but without triggering a region-wide, high-intensity conflict. A precarious balance might be achieved, for example if Israel halts the in-your-face elements of its expanding occupation, a reinforced UN Interim Force in Lebanon (UNIFIL) takes up position on both sides of the Israeli-Lebanese border, US sanction enforcement against Iran is somewhat loosened and the axis of resistance, including Iran, observes a longer-term ceasefire regarding Israel.
