Recent Israeli strikes have killed the leader of Hizbullah, Hasan Nasrallah, which could have unpredictable consequences in the region.
Weakened by these attacks, Hizbullah is now in search of new leadership.
Iran could become more directly involved in the conflict, despite the risks of confronting Israel and the US.
Constant Israeli attacks increase the possibility of a ground invasion in southern Lebanon and hence a regional conflict.
Israel is simultaneously in conflict with Gaza and the West Bank, in addition to Lebanon.
Netanyahu is pursuing a military victory at any cost and his popularity increases based on international inaction and US support.
Conclusion: The assassination of Nasrallah by Israel, along with the potential Israeli invasion of southern Lebanon, could trigger a regional conflict with still uncertain outcomes.
