• Israel threatens to seize Lebanese land if Hezbollah joins Iranian attacks.
• Defense Minister Katz warns of expanded security zone in southern Lebanon.
• IDF prepared to launch invasion in response to attack.
• Hundreds of thousands of Lebanese remain displaced from southern Lebanon.

This threat may indicate Israel's growing concern about Hezbollah's involvement in Iranian attacks. The potential expansion of the security zone suggests a shift in Israel's defense strategy, which could lead to further escalation in the region. The threat may also be a political move during election season, which could impact the outcome of the elections.
