US President Donald Trump vented his frustration with Israel’s military campaign in Lebanon, going as far to suggest that Syria would do a better job fighting Hezbollah there.

During a meeting at the Group of Seven summit with Qatar’s leader, Trump said Israel’s campaign against the Iran-backed militant group had nearly derailed peace negotiations with Tehran. Trump’s suggestion is a clear jab at Israel. Syria is a longtime adversary of the Jewish state and Israeli leaders are deeply suspicious of the new government in Damascus.
