Russia continues to be the armory of evil.

TEL AVIV—As Israel advances its invasion of southern Lebanon, its troops are finding large troves of Russian weapons, confirming longstanding suspicions in Israel that Hezbollah is enhancing its fighting capacity with the help of sophisticated Russian arms.

Some of the weapons, which include modern Kornet antitank missiles manufactured as recently as 2020, were sent to southern Lebanon in recent years from Russian stockpiles in neighboring Syria, according to Syrian security officials and an Arab official. Russia has long provided arms to Syria’s military, as well as controlling its own warehouses in the country.
