Analysts suggest the instability could derail the agreement, as it introduces a new and volatile element into the already complex geopolitical landscape. The situation in Lebanon is seen as a potential flashpoint that could escalate regional conflict, complicating diplomatic efforts. Concerns center on the possibility of miscalculation or further escalation leading to wider repercussions. The potential collapse of the Iran-US deal would have far-reaching consequences for regional security and global non-proliferation efforts. Observers believe a stable Lebanon is crucial for fostering a conducive environment for successful negotiations.
