The last time israel invaded lebanon in 2006 they got their ass handed to them by hezbolla. Israel lost quite a lot of their merkava tanks. They were vulnerable to atgm’s fired from hidden positions. Now they will also have to deal with drones. Israel has been fighting in gaza since october without achieving it’s stated goals. As long as hamas terrorist leaders have sanctuaries outside Israel, and can field a dozen fighters they are not defeated. That’s how guerilla war works.. Also it would appear they’re not getting live hostages back; they’ve been killed by airstrikes or murdered by hamas.
