Has Iran's retaliation against Israel just begun?

Overnight airstrikes from Iranian allies Hezbollah in Lebanon have prompted discussion that their strike back against Israel has begun.
Right, so last night saw a massive attack launched by Hezbollah in Lebanon where at one point more than 100 rockets were fired from Lebanon into northern Israel and the occupied Golan Heights in an attack that has people debating as to whether or not this is the beginning of Iran’s revenge upon Israel for striking it’s consulate in Damascus, over which they have made clear they will be retaliating and have said they will do so through proxies, in other words forces allied to Iran acting on their behalf, though I wouldn’t necessarily rule out direct action from Iran itself.
Hezbollah are one such ally and where many people compare Hezbollah and Hamas in one way or another, pro Israeli’s might regard them as anti Israel terrorists, others more clued up would consider them resistance movements borne out of Israeli attacks and occupation both past and present in Gaza and Lebanon, but one key difference is that Hezbollah are far more powerful, and until the invasion of Gaza, there had been no escalation between Israel and Lebanon. Now this has ramped up again are they acting on Iran’s behalf or is this simply another separate escalation Netanyahu has brought down on his own people?
Right, so there has been a lot of conjecture about escalation of warfare across the Middle East, the Israeli attack on the Iranian embassy in Damascus has brought Iran into the regional conflict more overtly, though so far that has been a war of words, with the action still to come, the retaliation on it’s way, but last night’s massive attack by Hezbollah on northern Israel and the Golan Heights, occupied Syrian territory as that has been since 1967, was on a scale we’ve not seen in a long time, at one point 100 rockets falling on Israel in 15 minutes and it’s Iron Dome air defence system struggling with the scale of the attack.
So is this the start of Iran’..
