The IDF is losing the ground offensive in Gaza with an extremely high number of deaths and severe injuries (including mercenaries).
As many experts said before Israel launched this offensive it will be extremely difficult to defeat Hamas militarily on their turf.
The Israeli economy is tanking due to the war, there are still 100'000 displaced Israelis from the towns that border Lebanon.
So some bright sparks in Bibi's War Cabinet are arguing for starting a war with Hezbollah, so that Israel can get a "win" by returning the displaced Israelis to the North.
