Anybody who is rational will obviously agree that this are facts.
However you make it sound like Hezbollah is at fault here. What do you expect them to do? Declare another war on Israel? This will only make things worse for them than they are already. Even more so With Trump back in power and ful unconditional backing of Israel against any war to be fought against Hezbollah. So not a good thing at all for Hezbollah.
Moreover, I actually made a similar remark/prediction on this thread when this war was still unfolding middle of last year. I said Hezbollah made a mistake getting involved in the Israel/Hamas war since this will weaken Hezbollah militarily(not just in casualties of death and wounded) but even more so politically in the country as their internal political opponents will try and use the vacuum left by them(coupled with public opinion of those in public against the war due to damage and casualties they suffer) to take advantage of them politically in the country(which is normal as politicians around the world act the same). This is something they should have factor in their decision making which I think they neglect.
What I didn't expect was that Israel not only inflicted severe damage to Hezbollah and the country but they even took out most of Hezbollah leadership hence giving opportunity for political opponents in the country to make use of this vacuum which seems to be paying out now. This also had the unintended consequence of weakening the group and quickening the fall of their biggest ally and backer Assad in Syria who was the land bridge which Hezbollah could use to retreat and supply themselves as a land corridor which stretched all the way to Tehran. Now they are cut off from that and boxed in between 2 hostile countries now. The only way Iran can suplly them now is through which is more dangerous and complex as Israel can easily keep tabs or control it than before. An example just recently
Indeed Hezbollah is not in a good position. Things will be hard for them this coming years. Not as optimistic as they were before they decided to join the war unfortunately.
