Hassan Nasrallah and the terrorist group he led, Hezbollah, were responsible for killing hundreds of Americans over a four-decade reign of terror.  His death from an Israeli airstrike is a measure of justice for his many victims, including thousands of Americans, Israelis, and Lebanese civilians.

The strike that killed Nasrallah took place in the broader context of the conflict that began with Hamas’s massacre on October 7, 2023.  Nasrallah, the next day, made the fateful decision to join hands with Hamas and open what he called a “northern front” against Israel.
