The Iran–Israel proxy conflict, also known as the Iran–Israel proxy war or Iran–Israel Cold War, is an ongoing proxy conflict between Iran and Israel. In the Israeli–Lebanese conflict, Iran has supported Lebanese Shia militias, most notably Hezbollah. In the Israeli-Palestinian conflict, Iran has backed Palestinian groups such as Hamas. Israel has supported Iranian rebels, such as the People's Mujahedin of Iran, conducted airstrikes against Iranian allies in Syria and assassinated Iranian nuclear scientists. In 2018 Israeli forces directly attacked Iranian forces in Syria.

The Israeli–Lebanese conflict, or the South Lebanon conflict, is a series of military clashes involving Israel, Lebanon and Syria, the Palestine Liberation Organization, as well as various militias and militants acting from within Lebanon. The conflict peaked in the 1980s, during the Lebanese Civil War, and has abated since.
