Lebanon's parliament elected army chief Joseph Aoun head of state on Thursday, filling the vacant presidency with a general who has U.S. support and showing the weakened sway of the Iran-backed Hezbollah group after its devastating war with Israel.

Though Lebanon’s presidency is mostly symbolic, it has a few important powers, like approving prime ministers and cabinets. In a country still haunted by the memory of civil war, symbolism is important too: how the head of state is chosen says much about the balance of power in Lebanon’s factious politics.

Lebanon’s parliament has elected its US-backed army chief to be the country’s next president, ending a years-long political stalemate and presidential vacuum.
