The Israeli military says its Northern Command has approved operational plans for war with Lebanon.
Israel is ready for an “all-out war” in Lebanon and has plans approved for an offensive targeting Hezbollah, officials have said.
Israel and Hezbollah have been engaged in border fighting since shortly after the start of the war on Gaza, following the October 7 attacks on Israel. The confrontation is increasingly expanding, with both sides saying they are ready to go to war.
More than 400 people have been killed in Lebanon, including journalists and paramedics, over the past eight months, with 25 deaths in Israel. At least 90,000 people have been displaced in Lebanon, and more than 60,000 have been forced from their homes in northern Israel.
While this meme/picture is definitely exaggerated, the expansion of Israel far beyond its current borders is a political position held by members of the current government. It originates from early Zionist militias that aspired to capture these widespread borders.
It even caused an international incident some time ago. https://www.timesofisrael.com/israel-seeks-to-calm-waters-with-jordan-after-racist-extremist-speech-by-smotrich/
