Wouldn't surprise me. Hezbollah is essentially a proxy for Iran. If Hezbollah declares war on Israel or vice versa, then Iran would be dragged into the conflict, willingly or not. Iran doesn't want a direct confrontation with either Israel or the US.
They have enough issues as it is with the war in Ukraine having a big impact on them.
I tend to agree with others who believe the 2 conflicts are related as both Iran and Russia have been meddling in the ME for years, even decades. So calling the current conflict in Israel another front in a larger war males sense. Whether that evolves into WWIII idk, I just hope no one gets stupid with nukes.
