I don't think he did, at all.
The entire world is watching this now and it is blatantly obvious which side is escalating things, which side is treating even their allies with utter contempt, which side has zero regard for the safety of its own citizens held hostage. The usual rhetoric aside he basically said what Erdogan, most of the Arab world, the UN and its agencies, and nearly everyone else has been saying - that there has to be an immediate ceasefire to protect civilians, that the conduct of the Israeli government is creating huge tensions across the region and the only way those hostages will be released safely is via negotiation. At one point he even praised those around the world who have demonstrated in solidarity with the Palestinians.
The only side that want this to kick off further are the Israelis; they've proved that every day since October 7th with the deliberate targetting of journalists, the hospital bombings, the siege, the ramped up attacks in the West Bank, the repeated incursions into al-Aqsa and the rhetoric from Israeli politicians and media. Why would Hezbollah deliver what their enemies blatantly want?
Our and the EU political leadership probably have up to a week left of being ignored by the Israeli leadership before it becomes obvious to them that their position is untenable, and they'll have to align with the rest of the world. Even with US backing, once a reasonable proposal comes out of how to deal with this short of a UNSC resolution - a financial embargo for example - ends this war probably very quickly with the Israelis isolated nearly completely.
