Hezbollah does not need to win a war or escalate dramatically. It only needs to remain capable of triggering enough instability to pause the talks. Each flare-up in Lebanon functions as a throttle Tehran can pull at will — turning the costs of its proxy network into negotiating assets, and recycling regional liability into diplomatic leverage.
