Hezbollah, Iran’s most powerful regional ally, has signaled privately that it does not intend to attack Israel, but Lebanon’s military has bolstered its presence in the country’s south to prevent rocket fire.

In Syria, Iranian-backed militias have been largely expelled following the fall of Assad’s regime, stripping Iran of another key foothold in the region.
