The Middle East is on the brink of a wider war as tensions rise following the assassination of Hezbollah leader Hassan Nasrallah. There are concerns that the region could erupt into a regional conflict that threatens global security. The US has called for de-escalation and rushed military assets to the area, but there are doubts about whether it will be enough. Iran and Israel will play crucial roles in determining the next steps, with Iran potentially feeling compelled to intervene to save Hezbollah. However, there are reasons for Iran to exercise caution, including its own economic and political challenges. The situation is highly unpredictable, and the actions of both Iran and Israel will determine whether the region descends into full-scale war.
