Hezbollah, understandably is trying to avoid all out, large scale war. They are in a tough place because if they do launch a massive missile barrage against Israel that overwhelms their air defense structure and leads to any kind of mass casualty event, not only will Israel respond by unleashing hell on Lebanon from unchallenged skies, but it will draw USA into the war. Between 2 Carrier Battlegroups and dozens of relocated land based air assets, the United States has enough air based assets in the region to compliment the IAF and bring substantial destruction to vast portions of southern Lebanon, virtually unchallenged. An isolated, effective strike on one or two Israeli cities might mean the destruction of half a country that Hezbollah calls home.Hezbollah acknowledges that Qubaisi got whacked.
Heard an interesting thought from a Lebanese-migrant colleague today, that the Lebanese government/military should seize this opportunity, call up Netanyahu and team up to stomp Hezbollah out completely. Never going to happen of course, but I guess if the argument is supposedly "Hezbollah is not Lebanon, Lebanon is not Hezbollah", it's a hard proposition to argue against, makes sense. If they're such this thorn in your side and the country-as-a-whole doesn't agree with/support them, then yeah, now's your chance to come at them with actual backup.
That's a tough place to be in. You don't want to seem weak, but you also don't want USA to have a "defensive" excuse to join the war... Because guess what? Iran isn't coming to the rescue of their proxy if USA gets involved and F-35s and F-22s fill the skies above Lebanon, while Arleigh Burkes and nuclear powered submarines lurk off the coast... Iran is going to pretend they don't even know who Hezbollah is in that scenario.
