After the United States and Israel launched a large-scale military strike against Iran, the fighting in the direction of Lebanon has intensified. Israel has initiated a ground operation, aiming to expand the "buffer zone" in the south of Lebanon. The previously severely damaged Hezbollah in Lebanon has demonstrated "beyond expectations" combat capabilities, and the scale and intensity of the conflict between the two sides have exceeded the level of 2024. Some analysts believe that Hezbollah has restored a certain combat capability through the reorganization of its military structure. As the Israeli army pushes forward resolutely and insists on expanding the "buffer zone", the possibility of a protracted war between the two sides is increasing. Hezbollah's sustained combat ability, Iran's support for Hezbollah, and Israel's tolerance for casualties may jointly influence the course of the war.
