Full prediction
Over the next 30 days, absent strong external mediation, the Lebanon–Israel border is likely to shift from episodic flare-ups into a sustained limited war, featuring daily cross-border fire, targeted assassinations, and strikes deeper into Lebanon’s interior. Iran will increase advisory, intelligence, and materiel support to Hezbollah, while avoiding overt direct engagement, yet will be pressured to respond more visibly if Israel expands operations around Ali al‑Taher ridge or hits high-profile commanders. This protracted confrontation would devastate Lebanese border communities, strain Israel’s northern command, and heighten risks to Eastern Mediterranean energy and shipping. Confirmation would be continuous hostilities over multiple weeks and visible Iranian support signals; denial would require a robust ceasefire arrangement backed by US, France, and regional actors.
