Therefore, the U.S. argues, it is simply filling this void in self-defense by destroying the terrorists’ sanctuaries in Syria used to plan and execute attacks against U.S. civilians and troops as well as against Iraqi civilians.
The U.S. has a legally supportable justification for its actions in Syria. However, Israel’s justification of self-defense for its military operations in Lebanon to neutralize Hezbollah’s terrorist capabilities used against Israelis is far stronger.
The United States is not presently under attack by ISIS or al Qaeda, nor under an imminent threat of immediate attack. And while both terrorist groups have conducted numerous cross-border incursions into Iraq over the years, they have not represented a major threat to Iraq’s sovereignty and territorial integrity in recent times.
Israel, on the other hand, faces an immediate existential threat from Iranian terrorist proxies on multiple fronts, including by Hezbollah from Lebanon, as well as from Iran itself. Hezbollah, the strongest and most well-armed Iranian terrorist proxy, has launched its unprovoked rocket, missile, and drone attacks in violation of Israel’s sovereignty and territorial integrity from its bases inside Lebanon non-stop since October 8, 2023. The state of Lebanon has done nothing to stop Hezbollah nor would be able to do so if it tried.
Israel has the moral and legal right to take whatever military actions - when, where, and how it deems necessary - to defend its citizens from terrorist attacks by evildoers who want to destroy the Jewish state wherever they are located.
