Hezbollah’s furious reaction to the Israel-Lebanon deal unexpectedly signed in Washington on Friday is enough to indicate good news for Israel. The willingness of Lebanon to take full responsibility and to exercise its government’s sovereignty in the country’s south is extremely important. But the proof of the pudding lies, as usual, in the implementation. The previous agreement, which created even more favorable conditions for Israel and was signed in November 2024, was never fully implemented and eventually collapsed. Now, much depends on the ability of Lebanon’s government and army to impose their authority on Hezbollah – far from an easy task.
