Escalation of the Israel-Iran Conflict



Updated October 29, 2024


Overview

In October 2024, Iran and Israel exchanged attacks for the second time this year (see Figure 1 and Figure
2), after doing so in April. This resumption of direct conflict comes a year after Hamas (an Iranian ally)
led attacks from the Gaza Strip against Israel. Beyond Gaza and the West Bank, hostilities between Israel
and Iran-supported groups (the self-proclaimed axis of resistance) have flared in Lebanon, Yemen and
the Red Sea, Iraq, and Syria. U.S. forces and international vessels have also come under fire from Iranian-
supported groups. While the Biden Administration has repeatedly supported Israel's right to self-defense,
it also has sought to de-escalate tensions. Beyond the parties themselves, Israel-Iran escalation could have
wide-ranging implications for a host of issues, including energy markets, nuclear proliferation, and U.S.
global force posture. After Israel's October 26 retaliation to Iran's October 1 attack, a senior U.S. official
said that this round of direct Israel-Iran fire should be complete, and that U.S. forces were ready to help in
Israel's defense if Iran responds. Lawmakers may take varying stances on possible escalation or de-
escalation in the Middle East and efforts to support, restrain, or oppose the operations of Israel and other
key regional actors.
