Strategically - Hezbollah just needs to survive the current round. Israel has been the slow boiled frog - and it does not want to be the slow boiled frog anymore - so it is escalating to try and seek direct conflict to those who have been slow boiling it using its oversized conventional military power. Israel wants to provoke Hezbollah to a conflict so that it can move the dial to Iran.
Hezbollah needs to review and potentially replace its entire IT infra to see where the leaks are - but be a lot more smart about it this time. A closed ecosystem from China seems to be the solution? The reason why the west do not like Huwaei is because there are no back doors in Huwaei that they can exploit and it is alot more difficult for Mossad and the west to penetrate the Chinese ecosystem. Hamas hot not been penetrated to the same extent and you have to ask, why?
Also - Iran needs to realise it faces a real risk of actual war and it must re-equip its airforce and air defences as soon as possible. What is has now is not good enough - they need to be able to actively protect their airspace with a better integrated ADS that combines both SAMS and Fighter jets. Static defence around SAMs are not enough - you can see that in the Ukraine-Russian war.
Israel is in trouble strategically and they know it - the world has seen the real Israel and they dont like it and they dont want anything to do with it anymore - best to not fall into their traps on their demands on their schedule but to survive and if they wish to do so - to continue to boil the Israeli frog a bit more if that is in their strategic interests ?
